Tip 1: Disable Some Useless Programs at Startup


For some programs that runs at startup, you don’t use often but they still use big part of the memory. These programs would cause your PC run slowly. In Windows 10, you can disable these startup programs easily.

1. Press Ctrl+Shift+Esc keys together to bring up Task Manager dialog box.

2. Go to Startup tab. Select the program that you don’s use often and click on Disable button. Note you only can disable one program at once.




Tip 2: Update Drivers

Some faulty drivers especially faulty Graphics drivers would cause your PC running slowly. Try updating the drivers to fix Windows 10 slow performance.

Go to your PC manufacturer’s website to check for and download the latest drivers. If the PC manufacturer does not release Windows 10 drivers for some devices, go to the device manufacturer’s website and check for the latest driver there.

Tip 3: Change Pagefile Size


The pagefile is a virtual memory file which is stored in the root folder of your Windows drive. You won’t see this file until you set the system to show hidden files. When your system runs low on RAM (Random Access Memory), it will move some memory to pagefile.sys in order to run smoothly. The file is managed automatically by PC. But you can try changing the size for better PC performance.

1. Type “performance” in the search box at the bottom left of desktop and click on Adjust the appearance and performance of Windows in pop-up menu.



2. Go Advanced tab and click on Change… button.


3. Uncheck the box next to Automatically manage paging file size for all drives. Highlight the Drive that your Windows 10 is installed on. Select Custom size then change the Initial size and Maximum size to the Recommended size (In my case, the Recommended size is 1855 MB. Yours might be different.). After that, click Set button.



4. Click OK button.

5. Restart your PC for the changes to take effect.


Tip 4: Defragment Hard Drives


Follow these steps:

1. Type Defragment in the search box, and click on Defragment and Optimize Drives.


3. Under Status, select the drive you want to defragment. To determine if the drive needs to be optimized, tap or click Analyze.


4. Click Optimize.



Note: If you have a solid-state drive (SSD) installed in your computer, you should not defragment it, as degragment SSD won’t be helpful for PC performance but may reduce the life of the drive. 


Tip 5: Install an External SSD

An external SSD can give a speed boost. If are not sure how to install one, go to the PC store to have it fixed.


Tip 6: Upgrade your RAM


If you need to open a large amount of applications at the same time, maybe it is time to upgrade your RAM. After that, your computer would most probably run faster.


Tip 7: Remove the Crapware

Crapware could be the cause of slow PC performance. Uninstall them and see if your PC runs faster or not.
