The title/header in the notification for automatic reboot genereated by the patch managments settings looks off.
If the entire prompt could be more descriptive and say how many updates have been installed, must be restarted before <end date & time>.
"You need to restart your computer.
Your computer have been updated according to the company patch policy and needs to be restarted before to complete the updates.
(3) Updates installed, choose to restart the computer now or schedule it for a later.
Restart will automatically be done <date & time> if not performed earlier."
Something like this would make the users understand what is going on.
