For Windows and macOS devices, a restart notification warns end users when their computer needs to restart for a patch to be implemented.
What is a restart notification?
When a Windows or macOS device update requires a restart, a restart notification lets the end user know that a restart 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.
What does a restart notification look like?
The information in the restart 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:
Restart Notification Configuration
In general, the notification informs the end user that an update that requires a restart has been installed.
The restart notification message allows the end user to select from the configured deferral times. A menu indicates how many deferrals are allowed and for how long a restart can be deferred.
The typical configuration that Cyvatar implements for are:
- Deferral time options: 1 hour, 4 hours, and 8 hours
- The duration of time a notification message is displayed to the user: 60 minutes
- Number of times a user can defer: 3 times
For the example shown, if the number of deferrals is set to 3 then when the message appears the first time, you could select to defer 4 hours before the restart notification appears for the second time. Then you can decide if you need one more deferral before you want the device to restart. When the notification appears for the third time, the only option available is to select Options → Now (macOS) to restart. For Windows select Reboot Now. If you just ignore this message, the system restarts automatically after 60 minutes.
Note: Five minutes prior to a restart, the system sends a final notification warning.
Deferrals
Deferrals are the action of the end user delaying a restart according to the configured deferral times. Typically, Cyvatar recommends these duration options to be 1, 4, & 8 hours.
After the maximum of 3 restart deferrals is reached, the system will show only a "Reboot Now" or “Now” option, depending on your OS, and it will restart in 60 minutes if the message is closed or is not interacted with.
If the end user clicks the "Reboot Now" or “Now” option, the restart process is initiated, and the patch completes installation.
