So, I've been running win10 on my games machine for about ten months now, and there's been two 'reboot now or in 15 minutes, no other choices' updates that I've seen, and a sizable number of times I've come back to it having autorebooted to a login prompt. Usually I'm just gaming, but I've had it reboot with open documents.
I could probably turn this off somewhere, but as it's not a mission-critical computer, it's still amusing to me.
