Window has a warning that the license needs to be reactivated
Operating System: Windows 10
Windows 10 will check in with the on-campus license server on campus every 90 days or so. If the computer hasn't checked it, the Windows will deactivate until it's been re-authorized. This is typically seen on computers that have lived off-campus for a long time or, computers on-campus that haven't had an active network connection in a long time
