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 described — in my case, it wasn’t marked as “required.”
But your issue can definitely still be solved.

Could you run the following command in an elevated PowerShell:

DISM /Online /Get-Packages | findstr KB506881

Please post the output here.
With that, we can see the exact package name on your system and guide you to the correct removal command.
