KB4532693 update breaking user profile

So this happened to a customer, and I thought it was an isolated case, but it just happened in one of my computers too.

After installing the KB4532693 update, Windows fails to login to the current user profile, so a temporary profile is loaded. UVK/Quick user manager detect the corrupted profile and fix the registry key, but that does not solve the issue.

Reinstalling Windows 10 from the install media after fixing the corrupted profile does solve the issue. Uninstalling the problematic update with WAU Manager fixed it too. Hope this helps someone.

Just out of curiosity, both computers affected by this issue only had one user account installed. In my affected computer, uninstalling the update fixed the issue, reinstalling it brought it back.

Thanks Fred,

I just looked out of curiosity and my laptop has KB4532693 installed but I did not have any issues that were noticed. It is running Windows 10 Pro v1909 OS build 18363.657 with one user account installed. Strange things happen I guess.

KB4537821 for Win8 has a similar effect. Thought the first was a regular glitch until I had another one a few days later.

Thanks Xander I will check that out. Not sure it's worth it given the small number of Windows 8 computers out there...
