I did run my overnight computations and when I came to my computer, it is restarted :-( I am not sure why, but it is quite possible that it could have been automatic restart due to updates.
How do I stop Windows 10 from automatic restarts?
I have found this setting:
and I did apply it now, but is it enough to block all automatic restarts, even when I am not present at the computer and cannot react to the notification? In the past I noticed that some similar notifications had a countdown timer and if you didn't react, it restarted the computer (quite stupid, but that's how it SW nowadays...).
