Fix 3: Update your network driver

This problem may occur if you are using the wrong network driver or its out of date. So you should update your network driver to see if it fixes your problem. If you don’t have the time, patience or skills to update the driver manually, you can do it automatically 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 be troubled by the wrong driver you would be downloading, and you don’t need to worry about making a mistake when installing. Driver Easy handles it all.

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 steps (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3) Click Update All to automatically download and install the correct version of ALL the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

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

4) Restart your computer for the changes to take effect.

5) Check your computer to see if the Netwtw04.sys failed blue screen error has been resolved. If yes, then great! If the issue persists, please try Fix 4, below.


Fix 4: Run DISM

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

Here is how to run DISM to fix Windows corruption errors:

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 for the changes to take effect.

5) Check on your computer to see if the Netwtw04.sys error has been fixed.
