Not directly related to the content, but I'm wondering how you made that recording? The video has footage of the UAC desktop -- isn't that meant to be secure and inaccessible to normal applications like screen grabbers -- did you point a camera at your monitor, or is there some other way for apps to "see" that they're at the UAC desktop?

 I know you can try things like OpenInputDesktop(0,FALSE,0) and watch for failure to know if the secure desktop is up, but that's the opposite, that's _failing_ to get the desktop, not capturing images of it..
