What is a reboot notification?

When a Windows or macOS device update requires a reboot, a reboot notification lets the end user know that a reboot of their system needs to occur. This allows the end user to save any work that might otherwise be lost during a restart of their computer.

You must enable Automatic Reboot for the associated policy, and the policy must be active and scheduled.

What does a reboot notification look like?

The information in the reboot notification can differ depending on the operating system and how the message is configured.

For macOS users, a notification will look similar to this.

For Windows users, a notification will look similar to this:

What does a reboot notification indicate?

In general, the notification informs the end user that the device needs to restart because an update that requires a reboot has been installed.

The reboot notification message allows the end user to select from the configured deferral times. A drop-down menu indicates how many deferrals are allowed and for how long a reboot can be deferred.

The default deferral options are 1 hour, 4 hours, and 8 hours and the default number of times you can select from the available hours is 3 times.

For the example shown, when the message appears the first time, you could select to defer 4 hours before the reboot notification appears for the second time. Then you can decide if you need one more deferral before you want the device to reboot. When the notification appears for the third time, the only option available is to select Options > Now (macOS) to reboot. For Windows select Reboot Now. If you just ignore this message, the system reboots automatically after 15 minutes.

How reboot deferral options work

  • If the end user does not respond to the reboot notification in 15 minutes, the system will reboot automatically.
  • If the end user clicks Reboot Now, the device reboots immediately. When the device restarts, the patch completes installation.
  • The end user delays a reboot according to the configured deferral settings. After the reboot deferral maximum is reached, the system will show only a "Reboot Now" option and reboot in 15 minutes if the message is closed or is not interacted with.

How can I configure reboot notifications?

Administrators can configure reboot notifications when they create or edit a policy. To be able to send customized reboot notifications, you must select Enable automatic reboot after updates are installed.

For a detailed description of configuring reboot notification messages and deferral settings, see Managing End-User Notifications.

NOTE: Windows 7 devices will not receive a reboot notification. See also Supported Operating Systems.
