I guess everything went back to normal once you uninstalled the update?
I personally uninstalled it from my cloud-gaming instance (ShadowPC), as even ShadowPC sent an email to its customers saying this KB (KB5077181, but also KB5075941 if you're on the 23H2 branch) could make the system unreachable.
Hi there! At the moment, I'm running the latest update. I won't be rolling back or uninstalling so I can keep an eye on this :)
Is anyone else having issues in regards to this KB patch with their C drive reporting that its abnormally full?
