That was the first thing I turned off "UAC" I find it a pain, its just an obstacle for me, but i wouldn't recommend to anyone to turn it off as i do it for my personal use, I am the only person on this particular pc.
other pc's in the house have it turned on but not so it dull's the screen down though.
And i have just realized i have rekindled an old post, but still a valid question.
EDIT EDIT EDIT EDIT;
YES IN VISTA WHEN I HAD IT
AND YES IN WINDOWS 7 CURRENTLY
