Force Reader DC to update from command line

Summary: I need to find a way to have Reader DC look for and install updates on command without user intervention. I was hoping for some sort of command line option like: AcroRd32.exe /update

Does anyone know how to do this?

Details: We are setting up some computers to be used by students for training purposes and have decided to use a system to simulate the old Windows XP SteadyState to keep them from getting thrashed. The system we're considering allows for automated updates to be saved into the baseline but only if they can be triggered from a batch file or powershell script. I've searched around but found nothing. I know that DC auto-updates but if it does the update outside of the specified, middle of the night update window, the update will be eliminated when the system reverts to the saved baseline just before it starts the update period. It has to do the reversion to keep any malware and unauthorized changes that might have happened during the day from being incorporated into the new baseline. If I can't get the update to happen during this window, the system will be doomed to reinstall the latest version of DC each time it reverts (which could be several times a day). The alternative would be to find a way to disable the auto-update all together but then I would have to manually update the systems periodically. I'd prefer not. Any ideas?
