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!
