Fair enough, but you should realize that it's not asking you to confirm your action; it's asking your if you want to allow a certain program access to system files or administrative privileges. This would be useful, for example, if malware exploited your browser (presuming it's not IE 7 running in Protected Mode) and tried to write to the C:\Program Files or C:\Windows directories.

For me, this is a much easier method of running with restricted privileges than I have open to me with Windows XP. (With Windows XP, I run as a User and log into my administrator account to administrate my machine.)
