How to Fix WDF VIOLATION Error in Windows 10


Blue Screen of death is a painful experience for Windows users. This article contains the solution to fix WDF Violation error in Windows 10.

This BSOD error can appear on any PCs. For example, In last year, After the Windows cumulative update KB4462919, thousands of users have started encountering this BSOD. There might be different reasons. But, One thing is common. A big number of HP computer or laptop users had been experiencing this problem. But, We got a solution to get rid of it. In 2019, Many users are experiencing WDF_Violation error due to random reasons. However, you are in the right place for the solution.


How to Fix WDF Violation Blue Screen of Death Error

To get rid of this problem, we will follow several methods. Hopefully, Any of them will work for you. If you can’t boot Windows normally due to this problem, try most of these methods in Safe Mode.

1. Modify HpqKbFiltr.sys (HP Users Only)

The driver HpqKbFiltr.sys is one of the culprits. If you are an HP user, follow these instructions to modify that driver. It will fix WDF violation.

  • First of all, you need to go to recovery mode. Normally, After BSOD, Windows should automatically show you a window like the screenshot. From there, Click on advanced options to boot into recovery mode. If not, you can use a bootable Windows media to boot into recovery mode.

  • Now, Go to Troubleshoot > Advanced Options > Command Prompt.
  • Then, type the following commands and hit enter.
cd Windows
cd system32
cd drivers

ren HpqKbFiltr.sys HpqKbFiltr.sys.bak
  • After that, restart your computer and see magic.

Sometimes, It may say the system cannon find the file specified. In this case, Follow these things,

  • In the command prompt, type regedit and hit enter.
  • Then, Now, Select something and click on File and choose Load Hive.
  • It will open a new window. Just, Go to local disk C where you had installed Windows.
  • Then, Go to Windows/System32/Drivers folder.
  • After that, find and rename HpqKbFiltr.sys to HpqKbFiltr.sys.bak. You also can delete that driver if you can’t rename it.

It should rename that .sys driver and fix your problem.

Note: You may ask, why I used those commands. These commands rename that mentioned driver name to HpqKbFiltr.sys.bak. The location of this driver is C:\Windows\system32\drivers. When you open the command prompt in recovery mode, by default, it opens in administrator mode. So, you are already in the system32 folder. This command “cd drivers” is to navigate to the drivers folder. It will resolve the stop code: WDF VIOLATION as that command disables the problematic driver.

2. Update Drivers

If the WDF Violation comes suddenly and you can access Windows normally, this method is for you. In many cases, Outdated or corrupted drivers cause blue screen errors. So, you should keep all of the drivers up to date. In this case, You can Driver Booster or Driver Easy or any of these tools. These tools can update all of your drivers automatically with a single click.
