From Windows Vista or superior Windows added the User Account Control where you can control what can run, what can’t.
I turn my UAC off right out of the box because I receive all these confirmation messages that make no sense to appear being me the only user of that computer.
Windows 7 and 8 allow levels for the UAC. I wouldn’t be able to explain the details of the levels because I basically don’t understand the concept so I basically turn it off or leave it at level zero.
Whatch this video to help you getting rid of all the endless confirmation dialogs.
