One picture is a little off for "After completing 100 % installation of System Update, a prompt is displayed to restart the device."
That prompt is for BEFORE the System Update begins, not a prompt to restart the system.
This prompt is shown when "Show Progress" is enabled for the System Update and System Update is configured to use "Balloon Tips" instead of "Toast Notifications" to show the progress.
Set the ZCM Registry key 'ShowDefaultNotifications' to True and this prompt will not occur when 'Show Progress' is enabled and System Update will now use Toast, which is the Windows 10 default.
