We run a football pool at work, and as the IT guru I have been tasked with changeing the desktop background for all computers to show the status of the pool. We currently use GPO to set everyone's background to the same image, so it's just a matter of renameing a new image everyweek. Problem is, that requires the user to re-logon in order for that to take effect. I would like if when everyone came in, there screens were already changed. I guess I could just force a log off, but with over 200 users that could be rather time consuming, plus with all the computers being locked at the end of the night, who know what might not get saved if I force a re-log or reboot. Is there anyway to make the desktop refresh with out those options??
