I've been sick and had to abandon a huge amount of incomplete tasks, which manifested as several open tasks on my computer. There were multiple unsaved blocks of text pasted into instances of Notepad, multiple open browsers, etc.
Years ago, something flipped at Microsoft and they suddenly think it's OK to restart a computer for updates even if there are running tasks. This happened last night.
Rage.
[edit]
To the idiots:
-Having updates installed automatically WILL restart your computer without your permission if you leave it on long enough. THIS IS A FACT
-I said repeatedly that I *want* updates to be installed automatically (I have a good reason)
-I said "Install my updates automatically, plz."
-I did not say "Install my updates automatically and restart my computer when you feel like it."
You're the idiot, if you didn't realize this would cause your computer to automatically restart.
