oh my GAWD W10 just updated my nvidia driver to the latest buggy one without asking. that's why the system went down earlier today
what the fuck. thought i had that shit disabled.
btw this is a manifestation of one of the most incredibly mind-bogglingly awful things about W10: microsoft has made it Extremely Difficult to ensure your system stays up for any amount of time
on any day you might return to your PC to find it at the log-on screen, your system having gone down at some point in the last however-long you were away to apply almost-unavoidable patches
i've heard of it happening when people are on their system doing work, and losing work. it's so fucked.
@alyx yeah this is actually awful and the way to prevent it isn't too intuitive
though I've never had it reboot in the middle of me actually being at the computer, it happens when I sleep usually
you can also set "Active hours" during which it will definitely not reboot for updates (for a maximum of 18 hours)
mine are set to 09:00-00:00
@staticsafe so here's possibly the only working method to prevent W10 doing non-con driver updates
it's a complete hack

i am wondering why this didn't seem to happen to me over the last year of running W10. maybe i just didn't notice it updating...
