Vista UAC architecture information

To me, Windows Vista's User Account Control (UAC) is still something I cannot say I'd fully master. For this reason it's important that Microsoft publishes the details about this technology that soon (in few year's time, anyway) affects most of us. As part of the Vista Developer Story, there's an article titled "Windows Vista Application Development Requirements for User Account Control". Highly recommended reading for any Win32 or .NET developer!
