Mostly interested in doing it on some Win7 laptops, a lot of people seem to believe its not possible. However I can't find any definitive Microsoft documents detailing it either way:
- This old documentation (Server 2003) says its not supported
- This technet article details from May 2008 (& speaking about Vista) says 'Note that when your system is in sleep mode, it can still wake up at specified times to download and install updates'
- kb2799178 detailed that some Win8 PC's (mostly desktops) did support this capability via a setting in Control Panel->Action Center (& a 'Regular Maintenance' task in scheduled tasks)
Background: I have 20 Win7 laptops (Dell Latitude E5550) in a cart & I'd like updates to happen off-hours so users aren't bothered during work hours. We have a GPO that says to install them automatically & I believe it may make them restart
