Description
If you enable this policy, the PC will not automatically restart after updates during active hours. The PC will attempt to restart outside of active hours.
Note that the PC must restart for certain updates to take effect.
If you disable or do not configure this policy and have no other reboot group policies, the user selected active hours will be in effect.
If any of the following two policies are enabled, this policy has no effect:
1. No auto-restart with logged on users for scheduled automatic updates installations.
2. Always automatically restart at scheduled time.
Note that the default max active hours range is 18 hours from the active hours start time unless otherwise configured via the Specify active hours range for auto-restarts policy.
