quote: In past jobs I left my workstation on 24/7 and would always find it at the login screen after a set of updates along with the stupid balloon about how Windows happily restarted itself for me once I was logged in. My user account was centrally managed with limited privileges of course. And since the company had no IT person pushing out updates, MS was doing all of the work.So yes EVEN IF you're only logged in as a LUA, Windows will still perform the updates and reboot itself. If you decide to shut down, Windows will apply the updates without any privilege escalation, even as a limited user (and you'll get the 'do not turn off or unplug your computer' warnings).
