There is a trick where you use task scheduler to launch a program with elevated rights and without asking any password or confirmation:
Elevated Program Shortcut without UAC Prompt - Create
You need to know the admin password for creating it, but the shortcut works on its own after that. But be aware that this is a security risk as anyone can elevate without knowing a password. Be sure that the program don't have any backdoor that allows users to take complete control if they really want (open/save as dialogs are particularly powerful when running elevated).
