This policy setting allows you to specify when the user will be reminded to reboot the device after policies requiring a reboot have been provisioned on the device.  If you enable this policy, then you can specify the number of minutes after which the user is prompted to reboot the device after policies requiring a reboot have been provisioned on the device.  If you disable this policy, then the user will not be reminded to reboot the device after policies requiring a reboot have been provisioned on the device.  If you do not configure this policy, then existing device-specific policies that control the reboot prompt are applied.
