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 helps in the sense of once you’ve looked at code enough times, you can stop really seeing it. So many times I’ve debugged issues where I looked many times at an error that is obvious in hindsight but I just couldn’t see it before that. And that’s in cases where I knew there was an issue somewhere in the code.
Or for optimization advice, if you have a good idea of how efficiency works, it’s usually not difficult to filter the ideas it gives you into “worthwhile”, “worth investigating”, “probably won’t help anything”, and “will make things worse”.
It’s like a brainstorming buddy. And just like with your own ideas, you need to evaluate them or at least remember to test to see if it actually does work better than what was there before.
