Windows 7 would forcibly shut down and reboot, without warning or indication, if you delayed updates long enough. Any laptop I owned with 7 could and often did spontaneously restart, no matter what I was doing.

I'm not shy about installing updates, but if I'm busy working I would delay it a couple times. Then I'd not use the laptop for a few days (with it in sleep mode), by then I'd have forgotten about the update. I was bitten by forced reboots in 7 many times.

8 added a "Your PC will reboot in 15 minutes" and that was so much better from a laptop perspective. W10 insider builds currently tell you to set "inactive hours", and this works fairly well for both phone and laptop. My phone updates while I sleep, my laptop pings me to reboot at my leisure, for it is never awake & inactive.
