To deploy software, updates, and patches to Windows computers, while minimizing disruption to users, the university has established maintenance windows every Wednesday and Thursday morning. Windows computers in SCCM are powered on (“auto on”) at 2:00 a.m., and the maintenance window runs until 5:30 a.m.
It is a good practice to save your work and Shut down your computer at the end of your workday on Tuesdays and Wednesdays.
Generally your computer will reboot during the maintenance window but in some cases you may be prompted to restart your computer so the update process can complete and for your computer to function optimally. Shutting down your computer at the end of each workday generally alleviates this issue.
