As part of windows patch management, we are providing option to show reboot reminder. This option is applicable if the patch requires reboot after the installation. It is up to the patch behavior during the time of deployment.
This option is provided to make sure user data is not lost if we perform reboot in middle of system usage. It gives indication to the end user to save their work and allow the system to reboot.
Also, we have provision to allow admin to decide how long end users can snooze the reboot reminder. Once the snooze count is breached, then it will mandate user to reboot or the default action will be triggered. Refer below snapshots.
Please refer help link Windows Patch Scanning and Deployment Settings for reboot reminder configurations.
