At first UAC can surprise you, and there for annoy you. Y would I need to confirm the action I just asked for. And I’m no exception to this line of thought. However, I almost immediately remembered how Linux’s sudo command works and realized… aha!… Microsoft is trying to give the windows user the functionality advocated for YEARS by Linux fans. Not only that, but its actually doing it better then linux does for the most part. That is because in linux u usually only get an access denied and u need to re-issue the command using the sudo command, in windows with UAC u get prompted.
A lot more information about y UAC is a good thing and actually helps to keep windows secure, even for administrators, can be found in Marks Russinovich's presentation about it in MSs TechNet site:

For the people who don’t know who mark is, Mark is the creator of the famous ERD commander and the sysinternals utility suite.
