I want a Windows 8.1 Professional installation which is always running and accessed by users via RDP to install updates automatically and also reboot automatically if the updates require it, but this should only happen saturday night (at any other time the system needs to be running and available for users).
I changed the following registry settings:
4(Automatically download and scheduled installation)
0(also reboot with logged in users)
Unfortunately, this does not always work. It worked once when I set the
ScheduledInstallDay to thursday because I read in the documentation for
When this registry value is set to 1, you are still notified of the upcoming automatic restart on the sign-in screen. However, at the end of the three-day period, the 15-minute counter begins even if the computer is locked. The restart also occurs even if the computer is locked.
So I thought if I want the system to restart on saturday, I have to set the scheduled day three days before that, because the restart is delayed 3 days. But the system restarted on thursday. Therefor I set the scheduled day to saturday again, but now the restart did not happen at all (I always have to wait for the next update which requires a restart to test the new settings).
How do I have to configure the system so that it always reboots on saturday night if an installed update requires it, even when a user is logged in at that time?
Update: As there is still no answer, I'm starting to believe that I'm on a completely wrong path here. I would also be happy for pointers how such a thing should be done, e.g. how do you keep a remotely accessed Windows machine always up to date when there is a fixed time window for updates?
