There appears to be no straightforward way to permanently stop Windows 11 Home from rebooting on its own after installing updates. I looked for workarounds but so far I have only found a script that has to run on a schedule to block the reboot by changing “working hours”. (Link.)
Is that really the best that is possible?
I’ve heard so many horror stories about values getting reset by updates that I don’t trust it. That is to say, if my boss or coworkers told me this was what was required to keep the critical server from actually restarting then I wouldn’t test it.
