Suddenly your Windows 10 crashes and show you the blue screen Netwtw04.sys failed? On this post, I will show you several to fix it. 

Windows 10 is a modern operating system that offers you a modern work environment, current and focused on providing the best solutions for the end-user, but sometimes, as in many programs and apps, a series of errors can affect the optimal performance of the system.

One of these errors is the netwtw04.sys failed error, which is usually accompanied by the following message: Driver_IRQL_NOT_LESS_OR_EQUAL Netwtw04.sys

This error is displayed every time a particular app is started or when the headphones are disconnected and shows you BSOD (Blue Screen of Death).

Some of the causes of this error are

  • Outdated or conflicting driver
  • Incompatible Programs
  • Corrupt system file logs
  • Incomplete or missing Windows 10 updates
  • Hard Disk Damage
  • Presence of malware or viruses on the computer

With the following methods, I will show you how to fix this error quickly.

Method #1: SFC

Windows 10 makes use of logs in its file system to function correctly and expected by everyone, but it can be affected by some internal error that ultimately affects some system process triggering the indicated error.

Windows operating systems have an integrated utility that allows you to make an in-depth analysis in search of some error in the file system and, if it exists, proceed to repair it. This tool is SFC (System File Checker)

To make use of it, you need to follow these steps:

  1. Click on the Start Menu and type the word: cmd
  2. Rightclick on Command Prompt and in the menu select Run as Administrator
    command prompt administrator
  3. Once there, copy and run the following command: sfc /scannow

  4. Once the process is finished, we will see the results based on the analysis generated.

Method #2: Scan Windows

It is always ideal to have some antivirus software that allows you to maintain a level of protection in the system and its apps, and for this, you have multiple options, both free and paid.

In case of not wishing or not having any of these apps, you can use the integrated Windows 10 solution named Windows Security Center.

  1. Double click on the Windows Security Center icon located in the taskbar

Method #3: Update Network Drivers

As I indicated at the beginning, one of the causes of the netwtw04.sys error is produced by outdated drivers, but its update process is simple and can be done in different ways.

Remember that as Windows 10 releases new updates, features are added that can create some conflict with the current driver and hence the need to update the driver.

  1. Rightclick on the Start menu or use the keyboard shortcut Win + X and in the list select the option Device Manager
  2. Once there, open the section Network adapters

  3. Rightclick on your default network adapter and choose the option Update driver
  4. You have two options there, and I recommend to use the Search automatically for updated software option.

Windows 10 has a functionality named System Restore which allows you, as long as this option is enabled, to make the operating system return to a previous point of time where it worked correctly.

So you can go back to an earlier date where everything worked correctly and be able to fix this error.

  2. On the box copy the command control and press Enter
  3. Once in the Control Panel, navigate to System and Security and then to System
