It probably can, but that's not the point. Why even include it as a security feature if it sucks so much everybody turns it off?

Much of it is the same UI with a different paint job. There are some dialogs I recognize from back in the NT days, just with prettier colors that you could pretty much achieve with XP using a theme utility. This is especially true for many administrative utilities, with the main pleasant exception of the reworked Performance Monitor.

Because then you can blame it on the users when the OS gets owned by a trojan.
