I blogged several times already on UAC as this has been (and partly still is) a very disputed security feature in Windows Vista (which I still support!). I just found today a not really new blog post on UAC, which I think is worth reading. It is from April this year and is called UAC: Desert Topping, or Floor Wax?

Even though we could disputed whether UAC in some forms is a security boundary or not (this is addressed in the post), I think it gives some very interesting views on the debate about UAC
