Path in the GPO console
Computer Configuration\Administrative Templates\Windows Components\Windows Update\Legacy Policies Description
Enable this policy to control when notifications are displayed to warn users about a scheduled restart for the update installation deadline. Users are not able to postpone the scheduled restart once the deadline has been reached and the restart is automatically executed. Specifies the amount of time prior to a scheduled restart to display the warning reminder to the user. You can specify the amount of time prior to a scheduled restart to notify the user that the auto restart is imminent to allow them time to save their work. If you disable or do not configure this policy, the default notification behaviors will be used.
