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 like how, once AI is invented, there is never a problem that isn’t AI related.
Microsoft made broken shit before AI, it isn’t like they suddenly lost that capability once AI was invented.
It’s more like the old adage but extended: “To err is human, to really foul things up you need a computer, but to make an unbelievable mess you need an AI.”
That is certainly true and may very well be the case here.
It could also be the case that a human developer forgot to bounds check an array and iterated out of bounds, corrupting some important kernel variable. We won’t know unless we get a postmortem.
