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.
It sounds like user error to me. There is like 2 settings on onedrive and they couldnt even be bothered to configure it yet hes going through all this complicated troubleshooting.
If you can’t log into Windows you can’t change its OneDrive settings! What’s more, the user had no idea what was causing the problem, be it OneDrive or something else, until he did that troubleshooting! And, just setting up a new phone shouldn’t make your computer unbootable for any reason! Geez, way to victim-blame there.
