This morning, I was hit with a major problem when all of our clients—over 40 companies—started calling in at once. They were unable to log into their Windows 11 machines. After entering their passwords, the system would just hang on a black screen. Eventually, we figured out that the issue was tied to a recent system update, KB506835, which seemed to be incompatible with domain-joined devices. I managed to deploy a script through our management software, Atera, to uninstall the problematic update, and that did the trick—everyone could log back in. It was a rough way to start the Monday, especially since the problem affected both Active Directory and Entra joined devices. I apologize for not providing more detail initially; it turned out to be quite a hectic situation for us.

There's a thread discussing this issue—do your clients use Duo authentication? It could be relevant to the login woes. Check it out: [link]
Hmm, could this be related to the AWS outage? Seems like a lot more than just a simple update issue.“
With the limited details you gave, it's hard to say for sure, but congrats on resolving it? Also, just a heads up, it's actually Tuesday, not Monday. But I get it, things can get mixed up!
Yeah, the post was confusing because the update threw everything off. I was just focusing on fixing the login issue.
It sounds like your management software might not be playing nicely with the update. We didn't encounter any issues on our end aside from the usual rare black screen errors.
That could be it! Atera really saved us with the scaling issue to uninstall it. This is the first time we've run into anything like this.
Haha, maybe they're in a different time zone? It sounds like a huge hassle regardless.
