Oh and also this was wondering me:
You know that from Services we can disable a certain user group or a use from shutting down the system right? But I reckon the way now is useless because: even though won't get the Turn Off button in his Start Menu, he could easily log off or switch user and shut down from the Welcome Screen. This is really annoying, as I can't stop some of my Limited Account users shutting down this computer.
So my suggestion is, once we disable the Shutdown for a particular user, the Shutdown cannot be displayed for him, not at least in the Welcome Screen. I hope this would happen in the next O/S.
