I have researched the issue with UAC and find controversy on both sides (imagine that). The one thing I find most interesting were some documents arguing the very fact that an MS employee says it’s not really a security tool?
Oh well the debate shall go one forever as most do but one interesting find I made was a way to elevate admin permissions without prompt, as a matter of fact there are a few interesting settings in there to play with for UAC. Of course there is a draw back that you must have Vista Business or higher I believe.
This setting is interesting
Some day I’m sure if its not certified it won’t install.
