I think it was back in 2018, there was a bugged mandatory Windows Update package that was corrupted for weeks.

The system would ask you to reboot the computer, at which point it would try to install the update. That failed with a bluescreen, requiring an automatic restore. This process took around 30 minutes on an SSD.

So far seems innocuous, but the thing is, as this was a mandatory update, after one or two days it would display an un-dismissable popup over the entire screen demanding a restart, which would repeat the process above.

This caused data loss in applications if the user didn't have the opportunity to save whatever data was in memory. Remember, the popup is undismissable, there were no ahead of time warnings, and the timing varied (so you couldn't even rely on "the computer will fuck up at 16:03" or whatever).
