I'm having a similar problem. It isn't exactly on point, but it relates to being unable to stop auto updates.
After installing an update, my computer won't start- it gets to the login screen, but the camera won't turn on to face-recognize, and when I try to enter the PIN the screen goes black. Computer basically bricks, except that I can force a shut down.
I've tried restarting in autorepair, which wasn't able to diagnose the problem, just told me the obvious: the computer won't start properly. I tried uninstalling the update in autorepair, then trying to reboot in safe mode, but no matter how I try restarting, the updates start installing before it fully boots. I can't figure out how to start the computer without the updates that broke it beginning to install, so I can't do any of the suggested options to turn off auto update, because I can't get to the desktop.
Since Microsoft is only providing bot replies, I guess I'll have to reset the computer.
