Microsoft admits Vista UAC was designed to annoy users and developers

"Microsoft has a way of rubbing people the wrong way sometimes. In fact, so many people dislike Microsoft because of buggy code, the way it runs over competition, and the fact that it is the biggest player in the industry, that you wouldn’t think that Microsoft would actively attempt to annoy users, but it has. At the RSA Security conference last week, a Microsoft official claimed that annoying users was the actual aim of the User Account Control (UAC) feature in Vista. Microsoft’s goal, he said, was to try to force smaller software vendors to write more secure code."
