Hi!
How did you manage to uninstall KB506881? When I try to remove it through Settings > Windows Update > Update history, Windows tells me the update is “required” and therefore can’t be uninstalled.

When I boot into Recovery Mode (WinRE), the patch doesn’t show up in the list of removable updates either.
I also tried System Restore as a last resort, but it messed up my installation and now the system is unstable.

Could you explain exactly how you removed KB506881?
Thanks!

Hi I was able to remove KB506881 normally using the same DISM method you mentioned and in my case it was not marked as required Your issue can still be fixed Please run the following command in an elevated PowerShell 

DISM /Online /Get-Packages | findstr KB506881

 Post the result here so we can identify the exact package name and find the correct removal command
