The following list describes scenarios you may encounter when performing Windows Updates through Barracuda RMM where a system reboot may not be desirable.
Please be advised that while Barracuda RMM provides configuration for Reboot Options, Barracuda RMM does not have any control of the reboot behavior and as per Microsoft Update, the Do not reboot option will only be used if a user is actively logged into the system.
More information on the automatic update settings can be found in the Plan Automatic Updates Settings from Microsoft.
