Windows 10 100% disk usage in Task Manager [SOLVED]

By Sophie Luo in Driver ErrorTechnical Tips Tags: DiskperformanceTask Manager

If your Windows 10 PC has slowed almost to a halt, but you have very few programs open, something may be causing your hard drive to over-work. (Here’s how to identify if this is your problem.)

This is a problem because when your computer’s hard drive is constantly working at or near 100%, it won’t have any spare capacity to perform other tasks, even routine operating system tasks. This slows everything down, and can make your computer totally unresponsive. 

This is a relatively common problem in Windows 10, but luckily, it’s usually not a hard problem to fix…

Try these fixes, one at a time

Here are a few fixes that have helped other users fix their Windows 10 100% disk usage problem. You may not need to try them all; just start at the top of the list and work your way down.

1: Disable Windows Search
2: Disable SuperFetch Service 
3: Perform a diskcheck
4: Reset Virtual Memory

5: Disable Antivirus Software temporarily
6: Change the settings in Google & Skype
7: Fix your StorAHCI.sys driver
8: Update your device drivers

Method 1: Disable Windows Search

To determine if Windows Search is causing your 100% disk usage problem, the first thing you should do is temporarily disable Windows Search, and see if your computer speeds up. If it does, you can permanently disable Windows Search

Temporarily disable Windows Search

Windows Search is what makes searching files on your PC much faster. If you don’t use it at all, or you have another search app, you can disable it completely. Disabling this service will stop the indexing of all files. But you will still have access to search, which will take longer time.

Here’s how to temporarily disable Windows Search and find out if it’s the cause of your 100% disk utilization problem. (Note that Windows Search will start again when you restart your computer.)

1) On your keyboard, press the Windows logo key  and X at the same time, then select Command Prompt (Admin)

2) Click Yes at the User Account Control window prompt. 

3) A mostly black window will then display. This is the command prompt window. In this window, type in the following command: 

net.exe stop "Windows search"

4) Hit Enter on your keyboard. 

Check to see if your disk usage and the performance of your computer improve. If they do, you should permanently disable Windows Search as described below. If not, move on to Method 2

Permanently disable Windows Search

If you discovered that Windows Search is causing your 100% disk usage error in Windows 10, you can permanently disable Windows Search:

1) Press Windows logo key + R at the same time, and type in services.msc

2) Locate Windows Search option, double click it to enter its Properties window. 

3) Change the Startup type to Disabled. Then click Apply and OK to save your change. 

Method 2: Disable SuperFetch

SuperFetch helps to decrease boot time and make must-load programs more efficiently. However, it has been identified as a potential cause of disk performance issues in Windows 8 and later versions of Windows, including Windows 10. Here’s how to stop this service:

1) On your keyboard, press Windows key and X at the same time, then choose Command Prompt (Admin).

2) Click Yes at the User Account Control prompt. 

3) The command prompt will once again display. Type in the following command: 

net.exe stop superfetch

4) Hit Enter on your keyboard. 

Wait for a few minutes to see if your computer starts performing better. 

Method 3 – Perform a disk check

1) On your keyboard, press Windows key and X at the same time, then choose Command Prompt (Admin)

2) Click Yes at the User Account Control prompt. 

3) The command prompt will once again display. Type in the following command:

chkdsk.exe /f /r

4) Hit Enter on your keyboard, then type Y to confirm that you’d like to perform the disk check the next time you restart your computer. Please make sure you have closed all of your applications first.

IMPORTANT: Disk check will start the next time you boot your PC and it might take some time to complete (could be a day for some). If, when you restart, you don’t have time to wait for the disk check to complete, you can skip it. You’ll need to reschedule it again, as described above, though. 

Method 4: Reset Virtual Memory

Virtual memory can be considered an extension of your computer’s physical memory. It’s a combination of RAM and a portion of your hard drive. When the RAM isn’t enough to perform a task, Windows will temporarily store files in virtual memory, then swap them back to RAM when required. 

To reset virtual memory:

1) On your keyboard, press Windows key and Pause/ Break key at the same time. Then choose Advanced System Settings on the left panel.

2) Go to the Advanced tab, then click Settings

3) Go to the Advanced tab again, and choose Change… in the Virtual memory section. 

4) Ensure the Automatically manage paging file size for all drives checkbox is NOT ticked. 

5) Select your windows drive (the hard drive or partition that has Windows installed on it – usually C:), and enter an Initial size and Maximum size for your virtual memory:

  • Initial size – This value varies, depending on your computer. If you’re not sure what value to use, just enter whatever the number is in the Recommended category. 
  • Maximum size – Don’t set this value too high. It should be about 1.5 times the size of your physical RAM. e.g. A PC with 4 GB (4096 MB) of RAM should have no more than about 6,144 MB virtual memory (4096 MB x 1.5).

Once you’ve entered your virtual memory values, click Set, then click OK to continue. 

6) Clear all your computer’s ‘temp’ files. On your keyboard, press Windows key and R at the same time, then in the Run form, type temp and hit Enter. This will invoke Windows Explorer with your Temp folder open, showing you all the temp files on your computer. 

7) Select all the files in the Temp folder and delete them. 

Method 5: Disable Antivirus Software temporarily

If you’ve installed antivirus or anti-malware programs such as Norton, Kaspersky, AVG, Avast Behavior Shield or Malwarebytes, you should temporarily turn them off or disable them to see if they’re causing your disk usage problem. If your computer’s disk usage returns to normal when they’re off, you should contact the vendor of the software to see if they can provide some help. 

Note that Microsoft has its own default anti-malware, Windows Defender. It’s automatically enabled even if you also have other antivirus applications installed. Even if you disable your other antivirus programs, Windows Defender is always there for you during that certain time range. So, no need to worry too much about temporarily turning antivirus off. 

If you use other antivirus and anti-malware systems, please consult their user manuals to learn how to disable them. You might also find these links useful:

How to stop AVG temporarily?
How to disable Avast temporarily?

Method 6: Change the settings in Google Chrome & Skype

For some, a particular combination of Skype and Google Chrome browser settings causes the 100% disk usage problem in Windows 10. Here’s how to fix those settings: 

Note that the wording on different versions of Chrome could be slightly different. 

1) In Google Chrome, click the three-dot icon at the top right corner and choose Settings

2) Scroll down to the bottom of the page and click Advanced

3) In the Privacy and Security category, make sure  Use a prediction service to load pages more quickly is turned off. 

4) Make sure that your Skype is not running. 

5) In Windows Explorer, go to C:\Program Files (x86)\Skype\Phone\

6) Right-click Skype.exe and select Properties

7) Go to the Security tab and select Edit

8) Click ALL APPLICATION PACKAGES and tick the Allow checkbox for Write. Then click Apply, then OK to save your change. 

Now check your disk usage in Task Manager to see if this has resolved the problem. 

Method 7: Fix your StorAHCI.sys driver

Note: A million thanks to our warm-hearted reader Javier for the following solution.

If you have tried all the above methods but still no avail, please see if this additional one helps.

The Windows 10 100% disk usage problem might also be caused by some Advanced Host Controller Interface PCI-Express (AHCI PCIe) models running with the inbox StorAHCI.sys driver due to a firmware bug. 

Here’s how to determine if this is your problem and fix it:

1) Open Device Manager by pressing Windows logo key and X at the same time to choose Device Manager

2) Expand the IDE ATA/ATAPI Controllers category, and double-click the AHCI controller

3) Go to the Driver tab and click Driver Details. If you can see storahci.sys stored in a path of system32 folder, then you are running the inbox AHCI driver. 

3) Close the Driver Details window and go to Details tab. From the drop-down menu, select Device Instance Path. Make note of the path, starting from VEN_

4) Type regedit in the search box of Start panel, then hit Enter on your keyboard to run Registry Editor. Then go to: 

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\PCI\ <AHCI Controller>\<Random Number>\Device Parameters\Interrupt Management\MessageSignaledInterruptProperties

The <AHCI Controllerhere refers to the name you see from step 2). 

The <Random Numberdiffers on different machines. 

5) Double click the MSISupported key and change the value to 0

6) Restart your computer after the change. 

Method 8: Update your device drivers

If the steps above don’t resolve your 100% disk usage problem in Windows 10, it may be caused by a device driver. 

You can automatically update all your device drivers to the latest correct version with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing. 

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

1) Download and install Driver Easy. 

2) Run Driver Easy and click Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to any flagged device to automatically download and install the correct version of that driver (you can do this with the FREE version).

Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).


Here’s how to identify if 100% disk usage is actually your problem.

Note that the following steps may take some time if your hard drive is being over-worked. 

1) Type “task manager” in the Windows search bar and select Task Manager

2) In the Processes tab, look at the % at the top of the Disk column. If it’s 100% (or it’s close and it has a red background), something is causing your hard disk to over-work. 

  • Windows updates ****** my laptop, it’s so slow that it’s impossible for me to try any of these steps.

  • Don K Johnson

    Restarted and its back to 100% again.

  • Don K Johnson

    that did it, dropped it down to 26%

  • Don K Johnson

    I did the first 3 and restarted my machine and it was back up to 100% again.
    Repeated it all again down to step 5, now I’m going to restart and see how it goes.

    Do you have any tutorials on the computer not seeing all of my memory? I have 32GB of Ram but it acts like I don’t.

  • Mohammed Al-Shehri

    What worked for me is: In Google Chrome, click the three-dot icon at the top right corner and choose: More Tools > Extensions, remove Cisco WebEx Extension, it is not enough to disable it, it has to be removed.

  • Jose Juan Llanos- Cheju

    This, thank you sire.

    Besides, if you can’t find the High perfomance option in windows because the last W10 update (like me), click on the battery icon and move the bar to the very right

  • Tony_x

    no way, still 100% due to windows update…

  • Shivang Sarawagi

    It worked 🙂

  • I tried the first step in the process and that worked. Just warranted a slow search of the computer. I then re-enabled the index and changed to “high performance” and low and behold, there was the problem.

    Very, VERY weird how that works… But hey, I’ll take it. I was ready to flip my room upside-down because of my disk running hard. Now I don’t have to! Thanks a bunch, Toby!

  • Omar Kamel

    it worked for speeding up the PC but the disk still 100%

  • You can also try to end task everything uses your disk more than 1 mb/s , it worked for me , good luck.

  • TheGamgubben

    For me step 8 worked, it was old disk configs it seems like. Well, that is good I guess, you got some money and I got my laptop back.

  • Tin Matleković

    I love you

  • Ikogenu Nugraha

    so my problem is with my windows 10 new update idk how to change the power option :v (ist run 1000% because im on low battery? im using my laptop low battery while chargering ist bad to do that ?)

    • Ikogenu Nugraha

      whoops typo there run100%*
      an is*

  • saoili

    Should have thought of a disk scan, which is what did it for me. Sat at 11% for hours and now works a treat. This is a great article. Thank you

  • Kate Woodcroft

    you gotta make a ‘create a new plan’ and select the high performance as the basis for it

  • Kate Woodcroft

    you gotta make a ‘create a new plan’ and select the high performance as the basis for it ….

  • Jentzen Fong

    Thanks ! I have been struggling for this issues for 1 and half year. Trying to search for the solution in internet, tried what they said but still not working…

    Until I tried your 1st solution( disabled window search) I can see my disk usage drop to normal range instantly.

    You’re a saviour man… even window developers don’t know how to solve this issue..

  • Amandeep Singh

    Awesome!!! Laptop Started working fine just stopping Windows search.

  • SH3P4RD117

    (Jan. 30, 2018)

    What worked for my laptop:

    Windows 10 Home 64-bit
    Version 1709
    Build: 16299.192

    Control Panel > Hardware & Sound > Power Options > Edit Plan Settings

    Click “Change Plan Settings”
    Drop Down Menu – Select current (or desired) power plan
    Expand “Processor Power Management”

    In here, my setting for “MINIMUM processor state” while plugged in was for some reason set to 100%. I dropped the MINIMUM to 5% and clicked apply.

    When I opened Task Manager I was able to watch the Usage % steadily fall back to expected values.

    I have no idea why this setting was set to 100% minimum, but I have had zero issues since correcting the value.
    I hope this helps anyone else who stumbles upon this thread.

  • Carol Sandu

    I had the same problem but with a twist, my internet was also not working while hdd was at 100% use so I changed my router with a spare one and it worked normal again.

  • Umair

    Wow. It works after first step. While other steps are also good to decrease processing of disk. Disable 2nd one can cause some hard disk health damage.

  • Doctor Doom

    Didn’t work. Windows 10 has made my laptop useless. Going back to Linux Ubuntu.

  • Thomas Schultz

  • Enzonino Momo
  • Wesley Aleshire

    When I click on the windows key and X at the same time, the list that pops up does not include “Command Prompt Admin”, I have Windows 10 and it is up to date, what is an alternative way to access this section?

    • Sophie.Luo

      Hi Wesley,

      You can press the Windows logo key and S together and type “cmd” in (without the quotation mark). Then right-click Command Prompt and click Run as an administrator.

      Have a go at it now. 🙂

  • vin c

    seeing everyone having success and mine immediately went back to 99%. I’ve done basically everything at this point… was hoping for the miracle elixir, but nothing. just got the damn thing all setup to my liking, and i feel like i’m gonna have to reset the whole laptop…

  • karasahin

    I fking hate W10

  • I’ve tried everything on this page and I’m still getting 100% disk usage with no read or write activity whatsoever. I hope one of your can figure this out for me. It’ll work fine for a few minutes and then go to 100% disk usage for about one minute making this machine impossible to use for that period. I am experiencing this problem on both my desktop and my laptop and am seriously considering just going back to win7 as both were stable on that OS. I’d rather keep win10 if possible but this is making it difficult for me to get work done. Thanks for any suggestions!

  • Man thanks a lot! I have troubles with my PC for almost week, I was doing memtest, replacing graphics card, removing autoruns, disabling overclocking and after that all I realized it is caused by my secondary disk usage to 100%. Your first command

    net.exe stop “Windows search”

    worked like a charm for me! THX

  • mr_xyzzy

    I discovered another cause of this problem, which took days to solve.

    Basically, even though the SATA AHCI drivers were up to date , they were essentially the wrong drivers. Needed to use the Intel Rapid Storage driver instead of the Microsoft one that Windows 10 installed

  • Jerad

    yours method worked immediately. 100%-0% in a second wow.

  • Ibrahim Afzal

    Awesome dude! You are a life saver. Worked like charm!!

  • Rico

    For me what worked was disabling Windows Defender… hope that will help some people as i had been struggling with this issue for days and tried all of the solutions found on many such guides. Try deactivating Windows Defender
    1. Double click on the shield icon in your icons on the bottom right
    2. Go to Virus and threat protection settings
    3. Turn off Real time protection // Cloud based protection // Automatic sample submission

    Once that is done, you will notice the disk usage dropping to normal levels.

    WARNING : Make sure you DO have an anti-virus installed

    Tried everything but Performing Disk Check resolved problem for me.
    It took some time to disk check and repair and restart (around 5-6 hours), but it did solved problem for me.


  • kelvin

    What I did was to turn off all services except microsoft services and do a restart and it works!

    windows + R then type msconfig, go to services tab, click enable all, then check hide all microsoft services, this time click disable all. Then u un-check high all microsoft services.

    All microsoft services would be checked now and just do a restart on your computer when you exit the dialogue box..

    thank you brother. u deserve lots of plata ..

      same problem
      anybody have a solution for this?

  • I got this issue in the last months, and apparentelly is fixed on my Thinkpad X240. Whatever I did – and I did ALL these instructions – worked for like 1 or 2 days and the 100% disk usage was back. Several times my X240 was stucked, and I needed to do a hard reset.

    What REALLY change this situation of upgrade the Windows 10 to the LASTEST version: the Windows 10 Fall Creators Edition is absolutelly the best W10 version that I ever got it.
    Disk usage now is almost of the time on 0% to less than 10% – even when I open Chrome or Word, it goes to near 100% but in 2 or 3 seconds, falls back. And I even using the original HD (Toshiba 7200 rpm), it´s not a SSD yet.

    I strongly reccomend the upgrade, because that was the only thing that really fixed the 100% disk usage issue, at least for me.
    But I reconfigured the new version with all these steps again, just for garantee that I am using a clean and stable OS. These hints here are absolutelly fantastic for a W10 user.

    The link that I used to download the W10 Fall Creators Edition was:

    Hope this can help other people like me that wa already getting nervous about using the laptop with this issue.

    In my case it was Facebook and Messenger apps. In task manager all kinds of things were showing usage at 60-70% level: antivirus, system, host services all taking turns. Uninstalled those two (since they’re lagging horribly anyway) and it’s normal now, reasonable disc usage for all those I meantioned and 1-2% overal.

    I’m really glad I found this: I was getting worried that my SDD was failing. The step that seems to have worked for me was Method 4, but I also applied Method 6 (since I do use Chrome and Skype).

  • John Shrubb

    My anti-virus was running the disc at 100%, I would recommend that if you are scanning for threats, make sure to leave to run with no programs running. This should help it scan quicker. Especially Eset.

    DEFRAG via Defraggler worked for me on my 75% unused 500mb Seagate HDD – I tried Power options = High performance + Anti Virus + Anti Malware + disabled Google Superfetch + disabled Superfetch, win search & BITS via services.msc + Custom RAM + HDD diagnostic + Uninstalled Skype….none of which made any difference. I then used defraggler to perform a long Defrag & that completely resolved the issue.

  • Jovana Đurović

    Toby, you are genius ! 🙂

  • purplevamp

    Did this after trying EVERYTHING else. So far it seems to have worked. Fingers crossed it stays that way. You have saved my sanity!!

  • Subham Kumar Patro

    Another method : Turn Off the cloud protection in the windows Defender. It worked for me.

  • Christopher Francisco

    Omg, Toby I love you man, it worked about 5 minutes after restoring to default. (I did everything on the list (except installing Driver Easy though)

  • Seemed to have worked for me! Thanks.

  • Malik Mazhar

    Toby you are an amazing person, tried everything but when looked into comments and changed power to high perf .. worked straight away .. amazing bro

  • Liz H

    I was working through the steps and nothing was helping. I decided when I got to the step about the suspending the antivirus, that I would uninstall McAfee which was on my machine for web browsing site safety only, I was using another company for the actual anti-virus. I had been meaning to uninstall it anyway for a while. That did the trick. I went from 100% to 2% I was shocked!!!

  • DemonEastz

    Thanks, they works~!

  • mcHasib

    You are awesome

  • Asta

    Can’t do options 1, 2 and 3 as there is no Command Prompt (Admin) listed when I do the Windows button plus X. And yes I am running Windows 10. Is there another way to do these methods?

    • Sophie.Luo

      Hi, Asta. To run Command Prompt in administrator mode, you can press the Windows key and S at the same time, then type “cmd” (no quotation marks) in the search bar. Right-click Command Prompt and click Run as administrator. You should be able to try the methods from there. If you need more assistance, feel free to ask.

  • Martin Suľa

    You are the best , thanks a lot , games are going best now , my laptop was in fix guy (i dont know how he is called in english) and he didn’t know how to solve it , i found you , and i solved it !! thanks alot !!!!

  • Katana Katana

    Thx buddy. Worked.

  • David Le

    Toby, great work. I will be recommending you for the Nobel Peace Prize.

  • Nick Peters

    Nothing on this page had helped me but when I went to delete the contents of the temp folder, there was one folder I was unable to delete because it was being used by an open application. It was a folder for Adobe Creative Cloud. I wanted to delete this folder so I opened task manager and closed Adobe CC completely and instantly my disk usage dropped to less than 5%. If you have Adobe CC installed, try closing it completely and see if that solves the issue.

  • Liz Fricke

    OMG You are a life saver <3 <3 <3 My computer would boot up and then immediately freeze. I did a clean install of the operating system from a USB and STILL had the same issue. Luckily after one boot up it ran long enough to turn that Windows Search thing off and now it works fine.

  • John Shrubb

    Thank you so much, I think you just saved my disc from exploding 😀

  • Dhanesh Edachana

    in my case, superfetch is caused the issue.

  • ExoticSharks 112

    this is amazing. my computer loads so fast now.

  • Peter Quagliano

    I believe my problem occurred after the 8-18-2017 Microsoft Office update for Office 2013. I uninstalled office, reinstalled it, and then set turned updates off. If appears that there is a Microsoft Office Upload Cache that kept using the disk space and kept it at 100%.

  • Oliver Olejár

    that worked <3 love you

  • D

    If none of the above worked follow me:
    1. Open task manager (Ctrl + Shift + Esc)
    2. Right-click Disk and set Resources Values for disk from values to percents
    3. Closely monitor the processes with high % disk usage
    4. Click on the arrow next to the most suspicious process to view its service
    5. Open Services (Windows key + R brings up Run, type services.msc and hit Enter key)
    6. Find the suspicious service and stop it, if disk usage instantaneously drops then,
    7. Right-click the culprit service, click properties and permanently disable it
    8. Done!

    • davesnrakleberger

      after spending all afternoon trying all the other options, this one worked like a champ..the trick was going from value to percents. Thanks very much.

    • Eyram Sotome

      You are the man… This worked for me!

    • Mihai Alexandru Hotca

      Thanks a lot ! This was very helpful !

  • Hanyoung Chang

    This worked, thanks dude.

  • Novac

    Thank you so much!

  • youskimad

    On my system Compattelrunner.exe was the culprit. This is related to application experience and turning it off immediately dropped my usage to 1%.

    The link that helped with relevant text in quotes is below…

    Using procexp.exe, I found that the offending process was started from a scheduled task, namely, Microsoft Compatibility Appraiser, which is found in Computer Manager under Task SchedulerMicrosoftWindowsApplication ExperienceProgramDataUpdater. There are three tasks in that folder.
    The description of the task says “Collects program telemetry information if opted-in to the Microsoft Customer Experience Improvement Program.”, so I suppose we can simply opt-out from the telemetry program and this should not run anymore. I believe that is in Settings->Privacy->Feedback.”

  • ViXplay

    Thanks, it helped. I bookmarked this page. Though when I start the PC it shows 100% disk usage, but after couple mins it goes to normal 1% or 6% and on and on.

    • ViXplay

      I just turned off Windows Search, for those who wonder.

  • din

    Antimalware Executable can also the main cause of this problem. You would have scheduled Windows Defender to do so. So I would suggest you to unschedule Windows Defender to do so and check.

    Follow these steps:
    a. Press Windows key + W and type administrative tools.
    b. Select Administrative Tools and select Task Scheduler.
    c. Follow this path in the left hand pane. Task Scheduler Library/Microsoft/Windows/Windows defender
    d. Uncheck all the boxes under Idle, Power and Network.
    e. Now it won’t scan your computer.

    • btrv32

      thanks so much! this helped a lot!

  • Cristian

    Hello guys, i tried everything above ,and almost everything worked, but till the next restart, everytime i did something it would work,for a moment,then come back to 100%, and I FOUND THE SOLUTION when i was fckin staring at task manager and seen that everything i open or do my Bitdefender check it first ,and just simply disabled it and magicaly dropped to fckin 0%… i was like no way… and it stay like that guys:D

  • Thanks Great Tips – Made an HUGE difference for my system

  • Aous Chazal

    I have done all the steps above, even the steps given in the comments (for Flash updates and high performance) but my hard drive is still used at 100% 🙁
    Any other suggestions?

  • Mark N Jackson

    Thanks! This problem has been bugging me for a long time. Computer gets so slow I can barely use it. Thought about buying a new one. So I disabled Windows search, boom! Disk usage is now 0 – 5%, instead of pegged at 100%, and computer is running like new. What a defective product Windows is!

  • Carol Ball

    Worked absolutely great! Thank you

  • Gunk

    I’m going to have to dust off my defunct Disqus profile to thank you for this, Toby. I’ve been struggling with this issue on and off for over a year and a half, and your tip just fixed it in ten seconds. Thank you.

  • Lhybrideur

    Solution 4 seems to have fixed the problem
    Thank you very much for compiling this

  • Pablo Gietz

    genius, this solve my problem disk can rest now …ASUS X556U

  • I did all of the recomended steps here, and nothing worked. Even swapped out the SATA cable.
    I also did a clean install from recovery wiping everything. But that was no good either.
    Mine went to 100% for no reason that I could find after every 10 minutes and stayed there….
    What seem to have solved it was to completely wipe the SDD by deleting the partitions. including the recovery partition, reformat the drive and download a new ISO from Microsoft, burn it on a memory stick and install from that. My system has been stable for 3 hours now. Will report back tomorrow, or when it crashes again.

    • Jae ウサギ

      broken hard disk could be the thing

    • jay613

      So, is it still stable 4 months later? I think the problem is that there is a Windows 10 update that causes some disk controllers to perform poorly. When you install a clean Windows 10 it looks great for a while, but eventually the update gets installed and slows it down. Did that happen to you? And you cannot stop Windows 10 updates.

  • Jide

    Using method 7, I didn’t find the MessageSignaledInterruptedPro folder. It wasn’t there

  • Douglas Celente

    In my case it seems like a Windows Update failed while in 9% and never ended (kinda looped). I went to Microsoft’s website and downloaded it manually. As soon as I clicked to start the installation, disk utilization dropped from 100% to almost 0.

    I must add: I tried every step from this page, as well as many of the ones suggested bby users (none worked for me). Also, this was a fresh install, so I did not have Flash Player on Update History.

  • Paulo Bombonatti

    Uninstalling Windows Search seems to have worked for me. But when I just stopped it, it seemed to start again. So it really solved it when I disabled it on Services.

  • Jay Valia

    don’t do anything except below..first try this one…sure shot…

    (1) go to google and search with your OS & board driver for SATA/AHCI controller

    Example : asus Asus H81m-cs sata ahci driver for windows 10

    Select driverscape website link and
    download the drivers
    (2) go to device manager and expand —IDE/ATA/AATPI controllers,
    select the controller and right click and update the driver and give path where you have downloaded
    above driver in step one.

  • K Sean Proudler

    Reinstall did not work. But I was still able to copy 2GB worth of files from the hard drive to a USB memory stick at the usual high speed. That was my quick hard drive check. The windows OS was the problem.

  • K Sean Proudler

    I disabled Superfetch, and Windows Search, and Windows Update. I rebooted and the problem remained. I restarted, and the problem had still remained.

    I then downloaded Microsoft’s Windows Malicious Software Removal Tool (MSRT).

    At first, as it begins to scan files, it is moving at a snails pace due to the 100% Hard Drive activity. However, after some time, it seems to have disabled many service programs, and then it takes off like a rocket. Once finished, I guess it re-enables the service programs, and does so in the appropriate order. The search itself had found no viruses. However, the 100% Hard Drive activity had completely stopped.

    So I rebooted and It was still OK. I then restarted, and it was still OK. Worked for me !

    After that, I went to power options and changed from balanced to high performance to see if that would improve things even more. Well the 100% hard drive problem instantly returned. So I reset it back to balanced, and the drive problem instantly vanished. So this one is a no go for me.

    It takes my computer about 2 1/2 minutes to sort everything out and bring the hard drive activity from 100% to 0% after power up, but I can live with that.

    • ben gonzales

      THANK YOU! I tried everything on this site as well as other sites and nothing seemed to fix the 100% disk utilization, until your trick –> MSRT. Like you said, it must disable and re-enable the service programs in the appropriate order. It did not find any viruses but the 100% issues stopped. After reboots and waking up, it will hit 100% for 2-5 minutes but goes to practically zero after that.
      Thank you again.

  • Estromback

    The skype thing worked for me, tried them all and the last one worked. THANKS!!

  • William Swarner

    microsoft support has helped me to re mediate this, im waiting on a backup drive then we re going to try a clean i install as the bug is an intermittent thing as he watched

    • K Sean Proudler

      I called Microsoft Support, and he basically said, put your hands in the air and hand me your money. $189.00, to be exact. I said bye bye.

      I had done a clean install, and it did not help. Near the end of the install it told me that it was having a problem starting my PC and said that this may be due to needing Windows Updates. I was given no choice but to carry on. The update(s) were the darn problem in the first place, so I was led right back to square one. The new Windows 10 Pro installed moved at a snails pace.

      Anyhow, as noted above, I managed to get the computer Windows OS up and working again.

  • Pulkit Vashishth

    Dude you are a life saver!

    Thank you. Disabling Windows search worked for me. However, I use windows search a lot and want to get that function back up and working again. Any ideas how to work around this? Would a reinstall of Windows fix this issue?

  • Option 1 worked for me

  • Giorgio Xenofonte

    I tried every solution avaiable (superfetch, win search, page file, etc…) and NOTHING WORKED.
    Then, someone said “TRY something weird: go in energy options and change from BALANCED to HIGH PERFORMANCE”…. AND IT WORKED.

    I dont know the reason. The person said it was a windows bug. Go figure!

    • Sophie.Luo


      In your case, we would suggest you contact the manufacturer of your PC to see if the support helps. From your description, the problem might not be the software.

      Also, please feel free to let us know if this happens to you before in the same machine.

  • Muhammad Nour

    thanks work for me 100% 🙂 now my pc so fast

  • David Kagawa-Aguirre

    First option worked for me

  • Zev Goldstein

    I found a permanent and complete solution to the 100% disk usage problem (sometimes it was 99% disk usage problem) by contacting my computer manufacturer, in this case, Asus. They said reinstalling Windows fixed it, at least on Asus machines… and although I was reluctant to do it since that’s the boilerplate Microsoft answer, I was surprised that it actually did the trick. I then implemented the above suggestions and my 3-4 year old computer is working like brand new, no problems at all with speed or cpu or memory usage.

  • visitor

    I will just add I had this problem on notebook and my friend also…i did killed some services and also virtual memory thing as listed here, but lastly we had discovered on both mine and friend laptop was the killer lan controler for wifi….uninstal it and instal only the pure driver if you have killer lan and this problem…but its rly unimaginable how many things in win 8 and up can do this kind of thing and turn your powerfull PC into 386

  • Silent

    Admin please add : uninstall any flash player update. To do so, go to windows update history and find flash player update and hit uninstall . Worked for me. I reckon, the problem is specific to device manufacturer. I’m using Windows 10 home edition on toshiba satellite p850.

    • HumanoidRogue

      You are an absolute life saver for this. Worked like a charm. Thanks

  • Nick

    This is a great guide and I’ve given all the steps in here a try, along with many other tweaks from various guides across the web. I was beginning to get to more advanced options and was about to give up and just reload my pc (time vs effort). I actually turned superfetch and windows search BACK ON and saw an instant drop in disk usage. Keep in mind I’ve had superfetch and windows search OFF for about 2 months while I attempted various ‘fixes’ and just kinda dealt with it. Who knows, give it a shot…

      Thanks for your comment Rory. Before trying anything else, I followed your example and unchecked Chrome’s predictive service, and my disk usage 100% to less than 5%. And Chrome’s memory usage dropped by half. I can live without prediction

      • Perry

        But now “Windows Modules Installer Worker” is hogging high amounts of memory and CPU. I just installed the latest Windows 10 updates this morning, so why is this even running and using up so much memory?

        • Harjot

          Same problem here

  • Lindsay H.

    I tried most of these solutions and it lowered my disk to 95-98%. I found that CompatTelRunner.exe was always near the top of the list on my task manager. This is some sort of Microsoft data collector. I went to the task library and found it then disabled it. Fixed the problem immediately.

    Not sure if that’s a permanent solution as it seems that even if you opt out of the data collection, it still runs and some people are saying that they are finding it running again after being disabled.

  • Anthony

    Very well explained Solutions.. Super Thanks… This helps me a lot… great job.

  • Avishai

    Great post, helped a lot!

  • Taker418

    Thanks a bunch disabaling superfetch and fixing my page file worked for me now I can use my laptop again for more than 5 min at time

  • bpn

    I have had this problem for a long time. I did most of suggested fixes. Probably everyone should do all of those. Because I am not sure what really fixed. For me all the suggested changes did not fix until I did following. But these suggested changes are needed to really fix. So do all of them including below what I did

    * Add more RAM
    * Adjust the pagefile to more than recommended. I doubled it.
    * I disabled cortana
    * I uninstalled skype completely
    * I uninstalled Norton completely

    • Natsu

      can i reinstall skype after that

    • ally

      It was CORTANA for me! Thank you! I have tried everything — I even almost threw this giant all in one down my stairs or even worse took it to geek squad or something. *facepalm*

      Ok I spoke too soon — I’m back up to 99%.

      I hate this thing.

    Thank you, thank you, thank you!
    This problem has been getting on my nerves for a while now. No matter what i tried nothing seemed to work.
    Found this followed a few of your steps, and then boom, a nice smooth disk usage.
    Superfetch never occured to me. I tried so many other services, but it was that one that seemed to be the pain in my… well, you know what.
    Thank you for this article. Life-saver

  • Rob

    Brilliant post, OP, most comprehensive I’ve seen, and I’ve searched this topic a bunch of times over the last year. Thanks! I disabled Search, no effect; disabled Superfetch, disk use dropped to “background normal” of 1-4%. Fingers crossed, that’s it. Why MS have Superfetch on by default I do not know. “Maintains and improves system performance over time” – really?! Ya think?!

    Superfetch solved it for me. Thanks!

    it fixes it for only a few minutes and then the disk usage percent hits 100% and my game freezes. help me please. i’ve tried every fix on this page and still nothing.

  • Khishigbayar

    Uninstall your chrome browser and skype. Then check your disk usage. Your disk usage could be 0%-2%. Good luck GUYS

    • Reyes

      That could be a great challenge LOL

  • Sam

    Hey, just have a problem that because my disk usage is at 100%, I can’t actually run command prompt as administrator. When I click to do it the screen fades (as if the “are you sure you want to do this” box is in the middle of the screen), but it isn’t. Any fix for this? Thanks

    • Sophie Luo

      Hi, Sam.

      From your description, it seems that there is something wrong with opening the Command Prompt in administrative mode.

      Please try the following methods:

      1) Try via another account. It could be a guest account or the admin account.

      2) Right-click the desktop – New – Shortcut.
      In text box, type cmd, then hit Next. Name it Elevated (so you know you’ve applied admin privileges).
      Now right-click this shortcut > Properties > Shortcut > Advanced > check off “Run as Administrator”.

  • Andika Azhar

    IT WORKED OMG THANKYOU VERY MUCH. Just did option one and two, and suddenly the disk usage droped to 3 percent. Thankyouuu <3

  • Glen

    Thanks so much for putting all this information together. I spent days working on the in-laws’ system after finally getting the Windows 10 upgrade to work, only to have it freeze about ten minutes after booting, with disk usage at 99% or 100%, and nothing visibly responsible for the usage in Task Manager or Resource Manager.
    I used the Show Services trick after following the additional links, added all the I/O columns to the view, and started stopping services. I finally got lucky on the first one I tried – Afcdpsrv.exe (Acronis Nonstop Backup Service). When I stopped this service and set it to disabled, the problem finally stopped.
    The installed version of Acronis TrueImage 2014 is 17.0.4515. There is an update patch available – I am not sure if it resolves this issue, but I will likely just uninstall the software, as it is not being used.

  • mahesh sakath

    Thanks for your guidance and support,i have solved 100% disk problem..Thank you so much:)

  • Ravi Kant Verma

    I tried all the tricks but you have suggested very good way to optimize the windows 10 as per the PC resource. Only by disabling windows search service my laptop become very fast and responsive further the hard drive activity becomes normal and now I again start loving my PC. Thank you brother.

  • dddd

    I cant turn off my windows defender

  • Anthony

    This is amazing now my computer’s disk usage has only 2% from 100%. Thank you so much for the tip.

  • glingace


  • Tristan

    Thank you so much, this finally helped me with my 100% disk error i’ve had for a while! Very good guide, 5/5!!

  • LouisXIII

    • Lemon

      OMG THANK YOU!!!!!!
      i kept getting 100 disk no matter what i did until i saw your comment and decided to try it.
      AND IT WORKED!! after like 10 seconds it went down to 1% disk and can start playing games again without lag.
      People, give this a try and see if it works for you.

    • Agustin

      I MADE IT BUT READ: I had to switch off Windows Defender Twice!!
      Don’t get tricked by WD, i went all guide on, including switching both options of WD off and got to the end of all guide with no change on that 100 % usage of disk at all, but as soon as i saw your comments, i went back to the Windows Defender shit and it was ON!!!!
      So i turned it off again and the RED COLUMN disappeared as well as the 100%. #2%4EVER

  • Josh

    Tried the stop commands and all said it could not be done.

    • Sophie Luo

      Hi, Josh. Could you please make sure that you are running the command in administrative mode? You need to choose Run as administrator when selecting Command Prompt. Please try again.

  • Chet

    Thanks after I disabled superftech it returned to normal

  • Bryn

    I have a friend running Windows 10 on a laptop, last night it said it was doing an update or something… this morning it was in sleep mode, when they login they get a blank screen with a flashing menu bar at the bottom, can get nothing to run except task manager. This shows Explorer.exe running at 80-100 CPU and the laptop gets hot with the fan working all the time. Stopped Explorer and CPU goes down to 6-10% and cooling fan goes off. But without Explorer nothing works… any suggestions? Cheers

    • Sophie Luo

      Hi Bryn. Are you sure that this only happens after the update? What was the update exactly? An update on the device drivers or the Microsoft Creators update? If possible, please consider performing a system restore on his laptop. The system restore feature is shut down by default, so he or she needs to turn it on before this problem occurs.

      If you need more help, here is a post for you and your friend:

      There are instructions of refresh and reset in the above post. If system restore is out of the picture, please have a try at performing a refresh.

    • Wayne

      I had the same problem and it was due to my second graphics card being disabled in the bios.

  • Peter

    Solve with step 1.
    5 stars rewiev 🙂

  • Ryan J

    I have a brand new computer acer i bought 2 days ago, did every step on the list and nothing changed… is this computer faulty? should I take it back? please let me know thank you! disk usage still at 100% that shouldn’t be the case for a brand new laptop right?

    • Sophie Luo

      Hi, Ryan.

      It seems that you need to take your newly purchased PC back to the vendor to see if there is anything wrong with the hardware.

      It is still very hard to say what are the causes of this problem. We can only hope that this is not triggered by hardware.

  • Justin

    So quick question anyone else here only have the 100% problem with a simple game running even everything at very low graphics settings, I see most steps are for if you’re just like on google or on desktop wondering if these fix game issues before I try them.

  • Subash S S

    Thank you. It did help me to reduce the disk 100% activity to 3%.

  • Sai Chaitanya peketi

    deleting the temp files(690Mb) by running %temp% in cmd itself reduced my disk usage from 100% to 5%

    • Geoffrey Nganga

      Best solution ever, del Temp files. It reduced mine to 1% from 98%. You are one in a million. Be blessed.

  • Michael

    Hi, is there a way to keep Windows Search disabled? I would disable it but every time I restart the computer it runs again. Any fix to that? Thanks.

    • Sophie Luo

      Yes, you can do that by following the instructions on Method One, in the section “If you want to disable Windows Search permanently”. It requires that you go to Services to make some change to the startup type of this service.

  • Joern

    Thank you sooo much! I only followed your first two steps and immediately my disk usage was down to less than 5%.

  • Chris Riley

    “Search index” with invalid entries in the control panel/index options was the cause of my issue. Realized it when stopping the search index service and killing the searchindex process in task manager. Had to stop both before it would release. C drive usage returned to normal. Immediately went into index options to uncheck those invalid entries, click ok. The entries cleared and Search Index started back up. After a few seconds was done, releasing the C drive again.

  • h1z1player18

    I noticed “windows update” and “windows module installer worker” at the top of my disk usage. I disabled them through services window and now my PC is back running smoothly. Now I’ll just have to update manually, which in my case is no big deal. As long as I don’t have to deal with hour long bouts of my PC being totally unresponsive.

    • random8888

      same for me, could you please tell me how to fix this in a little more detail thx.

  • Kirsten

    I managed to get rid of 100% disk space taken up notification by deleting my temporary memory files – clearing my recycle bin, clearing my browsing history and deleting unnecessary files in my downloads folder.

  • Thanks so Much

    the first option disabling windows search was so helpful it brought my disk usage down to zero thanks so much 🙂

  • Dilkhush

    When i was on the top of this page my Disk size was showing (99%-100%) now when i reaches at the bottom of this page i.e. comments box my disk size is now (1%-2%).(after following given steps)
    I recommended stop Windows defender that is option four.

  • Sergiy

    I can’t change the value on MSISupported to 0, it gives me an error and don’t let me change it, please help.

    • Sophie Luo

      Hi, Sergiy. Could you please take a screen shot of the error message that you see and then send it back to me? I will see what we can do from there.

      Thanks in advance for your reply.

      Looking forward to fixing this problem for you.

  • hiz

    My case was because of the adobe pdf reader update. After upgrading, the 100% problem has just gone. Hope this help.

  • Oskar

    In my case STEAM was causing this 100% issue :// Uninstalling took like 15 minutes (!!) but worked like a charm. Strange, it wasnt visible in the manager window!

  • Mylo

    i have a nice system that is being held back from disk usage problems. it happened directly following switching my motherboard, CPU, and RAM. i have tried everything in this post, tried several different versions of windows, tried a different HDD, tried different SATA cables and ports but i still get 100% disk usage every time im using an app or installing something otherwise it is normal during idle. anyone have any suggestions? (all drivers are up to date)

  • Andrew Maupin

    Thanks so much!!! Once I did the skype option, my disk went from 100% to 0% and there is no more lagging or freezing, thanks again. 🙂

  • Anu Shibin J

    Wow… worked for me

  • Daniel

    Thank you!

  • José Bozzo

    I cant believe it. I did the skype thing and my disk usage went instantly from 100 to 2% LOL… now its around 25-50 percent but it’s WAY better.

  • Danilo

    Thank you very much!

  • jesse

    Works so well, i could give the poster an hj

  • Brad

    Hi, I just wanted to say thanks for this thread. I tried basically everything suggested here in the article and comments, and nothing worked. Finally, I replaced the SATA cables to my two HDDs as user “A S” suggested, and it seems to be fixed the issue. I was skeptical it was going to work when I first read it, but I was ready to scrap my entire computer at that point, so I figured, what the heck, I’ll try it, and so far everything seems to be working great. So my suggestion to other users having the same issue and nothing else is working, try replacing the SATA cables before attributing the issue to faulty HDD.

  • Hugo

    Hi everybody. I had an annoying 100% disk activity problem on my main “C:” SDD drive (I also have 2 additional HDD with no issued) which appeared after 3 to 5 minutes of logging to windows rendering my PC almost completely useless. Although 100% disk activity, disk usage was only about 5%, so a service or program causing the problem was very unlikely and most likely there was a driver problem. I did’t see that so clearly at first, so I tried everything on this list… unsuccessfully. But finally I did solve my problem by upgrading my Intel SATA AHCI drivers to the latest release. That was kind of problematic because I upgraded to windows 10 from windows 7 with IDE SATA Controller so I had to follow online instructions on “How to Enable AHCI in Windows 8 and Windows 10 after Installation” in order to switch to windows’s standard SATA AHCI driver first and then upgrade to Intel’s latest driver using Driver Easy. It was only this last step the one that made my problem go away. Hope this help someone else!

  • James

    Hey there, i’m having a hard time deleting all the ‘temp’ files as part of the 8th process of option 3. When I select all the files, i get the message, ” this action can’t be completed because the file is open in Microsoft Office ClickToRun Service.” I have tried pressing ‘try again’ below but the same message reappears. Also, the only programs in the background whilst attempting to do this process is chrome, edge and file manager. Thanks

    • Sophie Luo

      Hi James,

      Please try restart your computer and then proceed with the delete.

  • Yash

    Actually the temp file part was the culprit I think, ran ccleaner and got 56 GBs of these and cleaning did wonders.
    Now it is at 5 %!!!

  • Josh

    Stopping superfetch worked for me.

  • Hamza

    Hey all
    I can’t do any of the suggested options because the high disk load is stuck on the Please Wait screen before the login screen, I’m running windows 10 latest build, the problem started after I updated to the latest 1607 build but not right away, it worked for a couple of days after the update then went south from there. Now I can’t do anything at all, tried a system restore to no avail. Any suggestions?

    • Sophie Luo

      Hi, Hamza.

      Please try the steps below to see if they help.

      1) First we need you to launch your Windows 10 into Safe Mode.

      It seems that you are unable to start your computer now, it is suggested that you perform a hard reboot.

      a. Press and hold the power button on your computer until it powers off.
      b. Press the power button on your computer to turn it on.
      c. Repeat step a) and b) until you see Please wait during the boot. It usually takes three repeats (more than three repeats if this is not the first time that you did this) for it to come up. You need to try until you can see the Please wait coming out.
      d. Follow the path: See advanced repair options > Troubleshoot > Advanced options > Startup Settings > Restart > click F4.

      If you can log into the desktop, please:

      a. Press Windows key and R at the same time;
      b. Type msconfig and hit Enter.
      c. From the System Configuration dialog box, click the Services tab;
      d. Check Hide all Microsoft services and select Disable all
      e. Navigate to Startup tab and choose Open Task Manager
      f. On the Startup tab in Task Manager, select each item and click Disable
      g. Exit Task Manager
      h. On the System Configuration dialog box, click OK, and then restart your computer

      Once you are in the Clean Boot environment, it is now time to pinpoint the service causing the problem:

      a. Enter System Configuration dialog box as before, and navigate to Service tab
      b. Check Hide all Microsoft services
      c. Select the upper half of check boxes from the list and clear the others
      d. Click OK and then reboot the system

      These steps will help you narrow the cause of your problem.

      If you can identify and locate the problem, you can disable the related programs or uninstall them.

      Also, you can try run a SFC scan:

      Hope this is helping you.


      • Hamza

        Thanks a lot for your reply.
        I will try to do that and report back.

  • IRAN

    I think this problem it’s with Antivirus. Stop that and see all things work normal

  • J.lee

    Hi there, I had a question. I’m having the issue with it being 100%, and currently going down the list to see if anything helps. I’m now at the virtual memory part… but don’t understand it whatsoever ^^; like, where do the numbers for the little bit of math come from? I prefer knowing lol. And like, what am I supposed to put for initial size… sorry, had me a little confused, so it may be a dumb question. And sorry if someone asked already. Thank you in advance.

    • Sophie Luo


      Sorry that I wasn’t making myself clear enough.

      To figure out what number you should set your virtual memory to, first you need to know the size of the RAM running on your PC.

      You can find this piece of information in Control Panel > System and Security > System. You should be able to see an option named Installed memory (RAM). Mark down this figure.

      For example, my RAM is 16GB, so the figure I should enter in the Maximum size box is (1024 x 16 x 1.5 = 24576 MB).

      The box for Initial size has already been filled automatically, you don’t need to worry about it.

      If there is anything we could to to help, please feel free to ask.

      • Janice

        Hi! I also would like to know the initial size. When I follow the instructions, the initial size does not appear automatically which is why I’m a little confused. Thank you in advance!

        • Sophie Luo

          Hi, thanks for the update.

          If the initial size box is not filled, please enter the same number that you can see in the Currently allocated category, which is on the bottom of the same window.

  • Rbbani

    Thanks for getting this done.

  • Angela

    Thank-you, thank-you, thank-you for this. I’ve been ready to throw my PC out the window.

  • Steve ex Mainframe

    Hello all – I have had this problem now for a quite a while. If I left the computer at the 100% disk it did sometimes sort itself out and was usable but then next time 100% again. So I started to apply the Option 5 but at the point where I was meant to highlight ALL APPLICATION PACKAGES – this line was NOT THERE! But today my wife said that Skype on her phone had updated and I wondered if there was a new version for my SONY computer using Windows 10. There was! so I updated (took a while as the old Skype was still hogging the disk) but eventually and after a reboot Skype is now running OK. So get the latest update – It MIGHT fix it. Give me my old mainframe computer – it never did this sort of thing!

  • ilmars

    Only one thing what helped me is – i turned off all my notifications in settings,and thats it. Easy ;). Hope it will help others too

  • Mark

    Every folks, Every time I restart my Windows 10 Pro desktop I get 100% for around 5-10 mins then all is good. I permanently disabled the Windows Compatibility process sometime ago and nothing obvious shows up in Resource Monitor since (various system processes). Before I try all the various suggestions above does anyone know if post startup 100% utilization is symptomatic of any particular issue ?

    • Kurt Straker

      Having disabled Windows search and Superfetch my son was still getting this problem on his i7 6700 Asus laptop with 1TB 7200rpm hard drive. Solution: I bought a brand new laptop which worked fine and was blazing fast until… he activated his OneNote account on it. The new laptop immediately slowed to a crawl and showed the 100% disk usage error. I asked him to reverse all the steps he had taken in setting up the laptop, last one first. The culprit is OneNote published by Microsoft Corporation and now included as part of the Windows 10 OS. I dug out the old laptop and booted it, It works fine until I start OneNote, disk usage immediately hits 100%, and when I End Task One Note it falls back to normal usage levels. I did this a few times and the result is always the same OneNote = 100% usage.

  • FredsterFW

    I’ve been trying every solution on the web for months now. Nothing has worked for me. None of the above. But I CRACKED IT THIS MORNING!!!

    Windows 10 seems to be super sensitive for the RAM configuration. I had 8GB + 2GB and it all showed as usable RAM in properties and Belarc. But my harddrive kept running at 100% all the time and sometime machine was unusable.

    But I took a chance and removed the 2GB and VOILA! Machine ran at full speed on one 8GB module without swapping to harddrive 100% of the time.

    Then I went a step further and swapped the two RAM modules to opposite slots and IT WORKED. All 10 GB working at full speed now!

    Hallelujah! P.T.L.! Seriously.

  • Jim

    I’m kinda over the edge to smash my notebook into some wall… have tried everything, Everything but disk usage remains at 100%. I have to leave the notebook for half an hour whenever it freezes, till the System process releases the disk. And mostly no processes are using much of disk but still usage is 100%. Its a Sony Vaio with an i7 and 12G RAM.

    I changed security from windows defender to avast/tried disabling, ran disk checkup, disk fragmentation,disabled Windows Search, disabled superfetch service, virtual memory is high enough, changed the settings in google n skype, don’t even use skype and tried other options too like updated All the drivers that needed to be updated.

    If there are any more solutions, please share!

    • Sophie Luo

      Hi, Jim.

      There are some useful tips in comment section that have helped a lot of users. Would you please also try them and see if your problem could be resolved?

      Thanks in advance.

      Please keep us updated. Thanks again.

      I can feel you mate… I’ve almost kicked my laptop yesterday when it got stuck for 20 minutes.

      It’s impossible to work with it 🙁

    • Jonathan

      I feel you Jim, I’ve almost kicked my laptop yesterday. It’s impossible to work this way. I’m always 100% sure that it’s a Windows 10 problem.

  • Clayton Sanchez

    One thing I did that seemed to make a huge difference is set the visual effects settings to best performance.

    In the file Explorer right click “this pc”
    Click “proporties”
    On the left click “advanced system settings”
    In the “advanced” tab click “settings” for the performance
    In the “visual effects” tab click the option “adjust for best performance”
    On the bottom click apply.

  • Kenny

    As soon as I disabled Windows Defender my pc took a sigh of relief suddenly I went from 100% disk usage to like 10%…

  • Cassandra

    I’ve had 95-100% Disk usage for a while now. I happened to notice a Windows Compatibility Telemetry running on the task manager a few times and just once, after months of dealing w/this issue, I noticed it was on the top of the list for usage for a moment.

    I googled & found this website:

    Instantly I was back down to 2 to 5% disk usage…Running very intense games on high settings, multiple programs…everything. I can get it up to 7%, but no higher.

    FINALLY…It’s taken almost a year, but my computer is finally cooperating properly again.

  • Kevin

    Hey I did option 2 & put the disk check to run …it’s been 2 hours since it started & it’s only been at 10% for almost all of that time. Is that normal ? How long should the disk check take ?

    • Sophie Luo

      Hi, the length of the time takes to run the disk check depends on the size of the driver and whether you have run the check before. For some, the disk check could take up to sic hours, for others, it could be one to two hours or just thirty minutes. It will take longer time if you are running Windows 7 operating system.

      If you suspect that the check is stuck somehow, please restart your computer, and then run the disk check one more time.

    • joe

      it took my computer about 6 to 7 hours to complete the diskcheck!

  • Javier

    My disk was 100% usage and the system blocked. I could see in the system event viewer some warnings with event id 129 about a device restart for storahci. It seems to be related to the windows disk driver. This link explains how to change the configuration for the AHCI driver and solve the problem:

    Now the problem seems to be solved for me.

    • Brian

      Javier had one to many beers and it all stopped working again the very next day.

  • A S

    Mine was caused by a failing SATA cable on a secondary non-SSD drive. Pulled my hair out trying everything but when the symptoms went away after putting a replacement drive in, then reappeared on that new drive shortly afterwards, even with all the services disabled and registry entry changed, I finally thought to try a new cable. Totally solved it, reverted all settings and have been good for a few weeks now.

  • Colin Reardon

    I had this problem for weeks. By chance, I switched off AVG Software Protection and the disk usage immediately dropped to 0%. I switched it back on and in seconds it was back to 100%. Switched it off again and back to 0%. I’ve left it off. Looking for Windows 10 problems appears to have been a wild goose chase for me.

  • Keith Taylor

    Quite by accident I tried to move a dozen video files off my disk to backup. Everytime I did this my pc locked up on one remaining file. Disk at 100%, zero traffic. Then I realised I had file backup on and it was freezing everytime it tried to copy that one file. Once it was deleted everything was fine.

  • alex

  • Krishna

    Thanks The Superfetch was the problem and it was solved now!!

  • Peter Quin

    thank you for all solutions. It’s finally worked for me after i did deleted all Temp files. if anyone still experiencing 100% disk maybe you should try this one first.

  • Joseph

    Okay so I have completed all of these steps and there is no change. I even tried some of the solutions in the comments such as disabling adobe flash player but that still didn’t work. I have heard about a problem to do with windows cumulative update [Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB3201845)] not installing properly. I don’t know if this has anything to do with the disk problem or not. When i go to settings/check for updates. It takes ages to find it and when it does it get’s stuck at 0%. I don’t know wether this could be a virus causing the disk issue or not. I disabled malwarebytes as said in the steps above so i haven’t done a check for any viruses yet. Do you think resetting the pc (removing all files and doing a re-install of windows) could be a solution to the disk problem and the windows updates? Thanks.

    • Joseph

      Just did the scan using malwarebytes and threats were detected. The cumulative update seems to have finally installed so i’ll restart and see if that changes anything.

      • Joseph

        *NO threats. my bad

        • Joseph

          The update installed fine. After the check and before the update my disk said 4-6% which is normal. After the update it was back at 100% again. From looking at my task manager out of what you can see, what is needed and what isn’t. This is usually much more background processes than i ever used to have. here are two images showing all of the current and background processes i have.

          • Joseph

            Is the top one malicious? my friend doesn’t have it in his so it could be a fake system 32 file (a disguised virus) Is it safe to remove?

          • Joseph


            This is a screenshot from my security task manager. The process at the top looks suspicious to me. Is it a fake system 32 file which is malicious? My friend checked his and he didn’t have it. I have a feeling this could be causing some of the high disk usage so should I remove it? Recently by the way my disk usage has gone back down to 0-4% on average and only occasionally jumps up to 99-100% when i open an app or when i go idle. Could you tell me if this is normal or not?

            • Sophie Luo

              Hi, Joseph.

              This .exe file is installed with Intel(R) Wireless Bluetooth(R) device driver. Some users report that this could be a sign of virus on your computer.

              Please use your trusted antivirus program to scan and see if you can detect any possible virus. If found any, remove them completely.

            I had my disk usage that mostly stayed between 80% to 100% and many times the pc would freeze, requiring hard-reboot. I implemented the settings yesterday. The disk usage still goes up after reboot but only for a few minutes, then comes down. So far, no freezes. I noticed in my task manager that the task which causes high disk usage is Service Host:Local Service (Network Restricted). This task periodically starts Superfetch service (the service appears as sub-task in the main task-list). During the time Superfetch is on, the disk usage becomes very high, before reverting to normal in a few minutes. Stopping Superfetch resolves this temporarily, until the next reboot, when it starts Superfetch again. I am going to observe for sometime. If I get any more freezes, I will disable Superfetch permanently by going to Services (run as Admin.. I think).

      KB3201845 is causing many problems, I uninstalled this update and all problems fixed. Used microsoft hide update: to block this from re-installing until it’s fixed.

        Uninstalling the last windows update is the only thing that worked for me. now drive is down around 2% as usually and not 98% – 100%

    • Chris C

      I had the same exact issue. I followed all instructions and nothing worked. (I even uninstalled Skype and Chrome, and disabled virtual memory entirely.)

      I tracked it down to the Windows Compatibility Telemetry process. Once I killed that, things went from 99% to like 12%. I then went and permanently disabled these two processes: “Connected User Experiences and Telemetry” and “dmwappushsvc” by right clicking on the start menu, choosing “computer management,” then expanding “services and applications” and disabling both processes.

        wow thank you Sir thats working 100%
        thank you for posting this

        I did not approve Microsoft to collect any info, yet it continues within task schedules etc. Disabled compattelrunner.exe (via services?) & then opened task scheduler & removed any CEIP entries. Now my laptop runs quicker & cooler. Otherwise MS will research your PC & it will slow to a crawl as they check EVERY file!

    Nice work on doing this. Unfortunetly None of this helped me solve my problem. The disk usage still spikes 100% at random moments and stays there almost all the time. The thing that gets this spike is almost aways the System itself. I already did a defragmentation, but it only solved it temporarely (about a day), did all the steps in here before, but no good.

    I did update my drivers recently, same for the BIOS.

    It’s an Intell Core i3, 4GB RAM, 1TBHD. Win10.

    The Google prefetch was my problem. 100% to 9% Disc. You are a Superstar and I cannot thank you enough. I have been battling for hours. I love you!

  • Abe

    Thanks. I tried your solutions and it worked. However, when i restarted my pc, the disk usage is at 100% again, whilst all the above have been set. Kindly help 🙁

    • Sophie Luo

      Hi, if you have tried all the options above and the problem remains, please try to disable your flash display to see if it helps.

      Type “chrome://plugins” in the address bar in your Google Chrome browser, then hit Enter. You will be able to see an option named “Adobe Flash Player”, click the “Disable” button under it. Then check to see if the disk usage is still 100%.

      Please feel free to contact me if the problem persists after this.

      • uday

        same is happening with me tried everythong but the disk usage is still 100%

        • Sophie Luo

          Please try the following procedure:

          1) Run Command Prompt as administrator.
          2) Type “wpr-cancel” (no quotation marks) and hit Enter.
          3) Then go to Task Manager. Go to Services bar, locate DiagTrack option (you can press key D to faster locate this option), right click it and choose Stop.

          Or you can try this permanent fix:

          1) Run Command Prompt as administrator.
          2) Type “sc stop DiagTrack” (no quotation marks) and hit Enter.
          3) Type “sc delete DiagTrack” (no quotation marks) and hit Enter.
          4) Open Task Scheduler (by typing task scheduler in start search bar), then go to Task Scheduler Library > Microsoft, delete the following items:

          Everything under “Application Experience”
          Everything under “Autochk”
          Everything under “Customer Experience Improvement Program”
          Under “Disk Diagnostic” delete only the “Microsoft-Windows-DiskDiagnosticDataCollector”

          Please let me know if it helps.

      I had the same problem, when I restarted Windows the problem came back but I tried disabling windows defender and the disk’s percentage of use turned into 11%. I hope it help you.

  • Jok

    It’s awesome. You’re great man!!!

  • David Torres

    The first time I did all of this it worked, I restarted my PC and the problem came back. I tried everything again, but it didn’t seem to work.I couldn’t do Skype step, since I don’t even have Skype. I’ve had this problem for a long time, but I remember that this didn’t happen when I first built this PC. My PC is not bad nor old. If someone has a solution please help me, I get stressed out no much, my PC got to the point of giving me a blue screen and after a restart telling me that i had a disk problem. PLEZ HELP…

    AMD FX 8350
    GeForce GTX 970 FTW EVGA
    Western Digital 1TB, “Black” I think

    • Sophie Luo

      Hi, David.

      In your case, it is suggested that you try to memorize the notification on the blue screen if it ever happened again, then go to our blue screen sections to see if you can find solutions accordingly:

      If you cannot find direct resolutions from these posts, please reply and inform me about the notification on your screen so I could be of further assistance.

    • Andrew Rushing

      I am also having the same results. It might be something to do with the combo of AMD FX 8350 and the GTX 970 EVGA FTW, because I have both.

  • Charlie

    I need help as well, as I am writing this comment, my PC disk usage is changing to 30% from 10%, and when I open windows explorer. I have tried all the tutorials available but non of them seem to work. I opened task manager and I see that “Google Chrome” and “System” has the highest MB/s. Any help on that will be HIGHLY thankful.


    • Sophie Luo

      Hi, Charlie.

      Have you updated your Windows drivers yet? Especially display drivers and network adapter drivers? If not, please do so.

      Also, if you can see an updated BIOS for your computer on your computer manufacturer, please download and update it too.

      You mentioned that Google Chrome is one of the applications that is hogging the disk usage, have you tried upgraded it as well? Or have you changed the settings as instructed?

      Please reply at your earliest convenience the update of your situation so we could provide further help.

  • Kaylee

    This completely solved my issue! Thank you so much, keep up the great work!

  • Genevieve Larsen

    Hooray! Had to try them all but the final step has seemingly fixed the problem. Thanks so so so much. GRL

    • Joseph

      Did you try the scanning and repairing drive step? I’m curious to know how it went and if you did it roughly how long did it take
