I have a confession to make. I’ve left UAC on on every single Vista machine I’ve used since using it as my primary OS in mid-2006 (Vista beta 2). On all but one of those machines I also run as a standard user without any specail permissions. Is UAC + least privilege a huge waste of time? It sure does seem so. Am I just slow to have taken this long to realize this? There has been sooo much vitriol and chest thumping about UAC it is hard to find any balanced discussions of it, and the impact of it on people who are already doing the right thing.
