KB5077181 was released about a month ago as part of the February Patch Tuesday rollout. When the update first arrived, users reported a wide range of problems, including boot loops, login errors, and installation issues.

Microsoft has now acknowledged another problem linked to the same update. Some affected users see the message “C:\ is not accessible – Access denied” when trying to open the system drive.

I think I'm affected because I can't locate a c: drive.

I'm using Mint, BTW.

I managed to park over half the c:drive. I drive an X5, BMW.
