REM Workstation Scheduled Reboots
REM Do you apply patches, and need to ensure the workstation is rebooting every once in awhile for the patches to take affect? This will determine the last reboot time, and if not within the past 7 days, schedule a reboot for Saturday at 2am. This requires the Windows remote registry service remain enabled and accessible (some workstation firewalls may block it).
