If your computer randomly crashes and you see a blue screen with the netwtw04.sys error code, you’re not alone. This is one of the most common Blue Screen of Death errors that are easy to fix. So, if you’re wondering how to get rid of netwtw04.sys error, you’ve come to the right place. We’ve prepared the steps needed in resolving this problem, allowing you to move forward with your tasks.

First Step: Entering Safe Mode with Networking

Do note that this method is just a pre-step that you must take if you cannot properly boot into your system. On the other hand, if you can log into your Windows 10 computer, you can proceed to the second method. That said, here are the steps in entering Safe Mode with Networking:

  1. Restart your computer.
  2. Once you see the Windows logo, press the Power button on your computer. Make sure you long-press it to turn off the unit.
  3. Repeat steps 1 and 2 until you see the screen which says, ‘Preparing Automatic Repair.’
  4. Windows will begin to diagnose the problems on your PC. Wait for it to complete, then click Advanced Options.
  5. Select Troubleshoot from the options.
  6. Click Advanced Options, then select Startup settings.
  7. Click Restart.
  8. Press 5 on your keyboard to enable Safe Mode with Networking.
  9. Once you’ve successfully booted into Safe Mode with Networking, proceed to the second step to troubleshoot the netwtw04.sys failed error.

Second Step: Rolling Back Your Network Adapter/WiFi Driver

In some cases, the netwtw04.sys failed error shows up because of certain network adapter/WiFi driver issues. To fix this, you can try rolling them back. Here’s how you can do that:

  1. Press Windows Key+R on your keyboard. This should open the Run dialog box.
  2. Type “devmgmt.msc” (no quotes), then hit Enter.
  3. Look for Network Adapters from the list and double-click it.
  4. Double-click your network/WiFi adapter.
  5. Go to the Driver tab, then click the Roll Back Driver button.
  6. Click OK.
  7. Make sure you click ‘Yes’ if you are asked to confirm the driver rollback.
  8. Restart your PC, then check if you’ve gotten rid of the Blue Screen of Death error.
  9. If you have both WiFi and network adapter drivers, repeat the procedure with the other driver.

Third Step: Updating your Device Drivers

As we’ve mentioned above, what might be causing the BSOD error on your computer are driver issues. So, if you’ve tried the second step and it didn’t work for you, then it is likely that you have an outdated network adapter/WiFi driver. As such, the best way to fix this is to update your drivers. This will keep the Blue Screen of Death error from progressing to a more serious issue.

When it comes to updating your device drivers, you have two methods to choose from—manual update or automatic update.

Manually Updating your Drivers

If you want to learn how to get rid of netwtw04.sys error, you must know the best way to update your drivers. Some prefer manually doing it, but the process can be time-consuming and complicated. The process involves going through the aforementioned drivers one by one to identify the specific culprit. You’d have to go to the manufacturer’s website and search for the latest, compatible drivers for the devices. If you install the incorrect drivers, you might end up doing more harm to your PC. So, you have to carefully identify the drivers that are compatible with your Windows system.

Automatically Updating your Drivers

If you do not have the skills, the time, and patience to manually update your drivers, you can automate the process using Auslogics Driver Updater. What’s great about this tool is that once you run it, it will automatically identify what system your PC is running. It will then look for the latest, compatible, and manufacturer-recommended versions of your drivers. This means that you do not have to risk downloading and installing the wrong drivers.


Resolve PC Issues with Driver Updater

Unstable PC performance is often caused by outdated or corrupt drivers. Auslogics Driver Updater diagnoses driver issues and lets you update old drivers all at once or one at a time to get your PC running smoother


Fourth Step: Running a DISM Scan

One of the great features of Windows 10 is the Deployment Image & Servicing Management (DISM) tool. It allows users to repair errors that are caused by system corruptions conveniently. In some cases, the Blue Screen of Death error happens due to misconfigurations and corruptions on the PC. If that’s the case, you can run a DISM scan to get rid of the error.

  1. On your keyboard, press Windows Key+S.
  2. Type “cmd” (no quotes).
  3. Right-click Command Prompt from the results, then select Run as Administrator.
  4. Paste the following command:

DISM.exe /Online /Cleanup-image /Restorehealth

  1. Press Enter, then wait for the process to complete.
  2. Type “sfc /scannow” (no quotes), then press Enter.
  3. Restart your PC and check if the Blue Screen of Death error has been resolved.
