Description

Specify the deadline before the PC will automatically restart to apply updates. The deadline can be set 2 to 14 days past the default restart date. The restart may happen inside active hours. If you disable or do not configure this policy, the PC will restart according to the default schedule. Enabling either of the following two policies will override the above policy: 1. No auto-restart with logged on users for scheduled automatic updates installations. 2. Always automatically restart at scheduled time.
