Rebooting without asking is terrible, even worse for me is the opposite, ie I want to reboot or switch off the machine, but when I try I get "Windows is configuring updates, please do not switch off your machine"
This is infuriating as hell when the reason I'm switching the damned thing off is because it's a laptop and the battery is about to run out. Even more infuriating when, to the best of my knowledge, the thing is completely up to date, it's been rebooted since the last update was installed, yet somehow, out of the blue, we get 20 minutes of "Windows is configuring updates......."
Yeah. Linux definitely never does that.
