Sorry to be a thorn in your side, pal, but I like hearing it straight from the team which designed it. They obviously know a bit more
(By the way, this little fact is one of those tidbits which can't be contested without making you guys look hypocritical and downright foolish in the eyes of those watching. If the original team said it's a security feature, you guys can't just backtrack
when you feel like it. Game, set, and match.)
The only thing we have stated regarding UAC is, one more time,
UAC IS NOT A SECURITY BOUNDARY.
