Fix the win32kfull.sys BSOD

changing driver to the Microsoft PCL XPS driver PCL6 driver Kxv4_v511708 may work for some users but the best solution is, to delete the patch which will undo the changes that were made. If you have installed the security update KB5000802 on Windows 10 20H2 or 2004 or KB5000808 on 1909 and encountered win32kfull.sys BSOD so follow the easy methods ahead.

  1. Open Settings > Update & Security > Windows Update.
  2. Click on ‘View Update History'
  3. Click on ‘Uninstall updates’ link.
  4. Locate the update and click on ‘Uninstall’.
  5. Select ‘Yes’.

 If it’s not possible to uninstall the patch through Control Panel, so try with following Command Prompt or PowerShell command to remove the patch manually:

wusa /uninstall /kb: [id]

In the above, it is needed to replace the KB ID with the one that you wish to uninstall.

If you’re on v2004 or 20H2, the command would be wusa /uninstall /kb:5000802. For version 1909/1903, the command is wusa /uninstall /kb:5000808.

Another solution is to switch to Microsoft PCL6 printer drivers or removing the printers completely (including drivers).

Once you’ve followed the above steps, open Settings > Update & Security > Advanced options and pause the updates.

If it’s not possible to uninstall KB5000802,

In the case of using Command Prompt or PowerShell, the process could fail with the following error:

Security Update for Microsoft Windows (KB5000802) is required by your computer and cannot be uninstalled.

In this case, rolling back to the previous version of Windows is needed by using the Recovery Options. If you don’t want to uninstall the update, you can also try the second, third and fourth method highlighted below.

  1. For advanced users, the second method requires you to enable Direct Printing which allows 32-bit apps to print on 64-bit OS without crashing the OS. regarding this solution, you need to follow below steps:
  2. Identify the name of your printer. (Eg: Kyocera TASKalfa 820 KX).
  3. Open Command Prompt (admin/elevated) and run the following command.

rundll32 printui.dll,PrintUIEntry /Xg /n "Kyocera TASKalfa 820 KX"

if the outcome is “direct “so it means that direct printing has been turned on, and this method will not help.

If ‘Direct printing’ is off, run the following command:

rundll32 printui.dll,PrintUIEntry /Xs /n "Kyocera TASKalfa 820 KX" attributes +d

In the above example, replace the “Kyocera TASKalfa 820 KX” text with your printer’s name.

If direct printing is already enabled and Windows is still crashing, you can try the second advanced fix involving Microsoft’s PrintIsolationAware feature:

  • Download the Application Compatibility Toolkit from Microsoft’s website.
  • After you’ve acquired the toolkit, you can now enable “PrinterIsolationAware” by following the guidelines outlined by Microsoft.
