For example, my wife had to work from home one day -- fairly rare occurrence -- and it was at that moment at 9:00am that Windows 10 decided to update and reboot with no way to cancel and the entire process took well over an hour. That should be unacceptable and I don't know why it's not. I have updates set to download but not install automatically and I periodically manually install them. Microsoft's active-hours thing is BS too as it must be less than 12 hours. I honestly don't care as much if my machine reboots between 1:00am and 7:00am but apparently that's not enough time.
