There does not appear to be a way to stop Windows from rebooting a machine that both (A) has pending updates and (B) does not have any active logged in users. Zcentral's behaviour on a client disconnect satisfies (B), and Windows will reboot -- even in the middle of full CPU load or other activities. Not cool.
Long story, short -- a system that should not be rebooted (The controller for a piece of scientific instrumentation, in my case) is automatically rebooted even while a user session is active in the background.
HP, this is REALLY bad. I realize that part of the blame falls on Microsoft for their heavy-handed auto-update policies, but an easy fix is to change the RGS/ZCentral behaviour to not lock the local console on disconnect.
Make it configurable, sure, but at least give us the option.
