If you keep getting random blue screens with netwtw04.sys lately, don’t worry. Here’re 4 steps that have helped other users resolve the problem. So read on and check them out…

Try these steps 

Step 1 is more of a pre-step than an actual fix for you guys who CANNOT log in Windows 10.

Just work your way down from

  • Step 1 if you CAN’T log in your Windows 10;
  • Step 2 if you can log in your Windows 10.
  1.  Enter Safe Mode with Networking  
  2.  Roll back your network adapter/Wi-Fi driver
  3.  Update your device drivers   
  4.  Run DISM

Step 1: Enter Safe Mode with Networking

1) Make sure your computer is off.

2) Press the power button to turn on your PC. Then when Windows displays a login screen (i.e. Windows has fully booted), long press the power button to turn it off.

3) Repeat 1) and 2) until the screen says Preparing Automatic Repair.

4) Wait for Windows to finish diagnosing your PC, and click Advanced options.


5) Click Troubleshoot.

6) Click Advanced options.

7) Click Startup settings.

8) Click Restart.

9) On your keyboard, pressto enable Safe Mode with Networking.

10) Now you’ve successfully booted up in Safe Mode with Networking, continue with Step 2 to troubleshoot the blue screen problem.

Step 2: Roll back your network adapter/Wi-Fi driver

Most Netwtw04.sys occurs because of network adapter/Wi-Fi driver issues. So we can try rolling back our network adapter/Wi-Fi driver to see if it fixes the problem. To do so:

1) On your keyboard, press the Windows logo key  and R at the same time, then copy & paste devmgmt.msc into the box and click OK.

2) Double-click on Network adapters and then double-click on your network adapter/Wi-Fi adapter.

3) Click the Driver tab > Roll Back Driver > OK.

If the Roll Back Driver button is grayed out, then move on to Step 3.

4) Click Yes once asked to confirm the driver rollback.

5) Restart your computer and see if the blue-screen-of-death(BSOD) issue has been sorted.

6) Repeat the driver rollback procedure if you have both network adapter and Wi-Fi drivers.

Step 3: Update your device drivers

As mentioned above,driver problems are the main culprit of this BSOD problem. And if Step 2 doesn’t resolve the issue, then your outdated network adapter/Wi-Fi driver is most likely at fault. So we might have to update our network adapter/Wi-Fi driver to prevent the blue screen of death from feeding into a more serious problem.

There’re two ways you can update your device drivers — manually or automatically:

Update your drivers manually – To troubleshoot the issue, you can update the aforementioned drivers manually ONE BY ONE until you pin down the exact offending driver. Firstly you’ll have to go to the manufacturer’s website, search for the most recent correct driver for the devices. Be sure to choose only drivers that are compatible with your variant of Windows system versions. Then download & update them all by yourself.


Update your drivers automatically  – If you don’t have the time, patience or computer skills to update your drivers manually, you can, instead, do it automatically with Driver EasyYou 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 the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.  

3) You can upgrade to the Pro version and 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.

You can also click Update to do it for free if you like, but it’s partly manual.

4) Restart your computer and hopefully it boots up properly.

If the problem still persists after using Driver Easy, feel free to contact our support team at support@drivereasy.com. Be sure to attach the URL of this article for more expedient and efficient guidance.

Step 4: Run DISM

DISM (Deployment Image & Servicing Management) is a tool in Windows that helps us fix Windows-corruption-caused errors. Sometimes this blue screen of death happens because of corruption and misconfigurations on our computer. If that’s the case, we’ll have to run DISM to check and fix the error.

1) On your keyboard, press the Windows logo key  and type cmd. Then right click on Command Prompt and click Run as administrator.

2) Type the following command and press Enter:

DISM.exe /Online /Cleanup-image /Restorehealth

Wait a while for the whole process to finish. 

3) Type sfc /scannow and press Enter.

4) Restart your computer and hope the blue screen issue has been fixed.

That’s it – 4 easy steps to help fix your Netwtw04.sys blue screen error. Hope everything goes off without a hitch on your computer and feel free to comment below if you have any further questions or ideas to share with us. 🙂
