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 worked at the Comcast Center back when Comcast was building a new skyscraper two blocks away. The reason for this new building was that the CC had become jam-packed with InfoSys contractors, like literally five or six developers jammed into one-person offices, floor after floor after floor. The executives – a majority of whom were Indian-American – wanted to see a lot fewer Indians around their headquarters (and they talked about this openly) so they built an entire new building to house them.
