Comment I prevent Terminal Serveur Users depuis redémarrering the serveur après an Automatic Mise à jour?

Nous avons a Windows Server 2003 terminal server, and our IT department does not want to disable Automatic Updates. Le problème est, when an update gets applied that requires a reboot, users get a popup about it and can hit Restart Now to reboot le serveur.

Is there a way to keep Automatic Updates on, but not give regular users the Restart popup after an update?

Disable the group policy allowing the notification to non-admins:

Computer Configuration > Administrative Templates > Windows Components > Windows Update > Allow non-administrators to receive update notifications

But, this behavior is the default - so either someone’s specifically enabled this policy in the past, or l’utilisateurs are admins?
