It's not a feature "yet."
Frankly they delivered a P.O.C. and hoped everyone would like. Sorry, but not a single Vista machine at home or office has UAC enabled anymore. I'm calling UAC a total failure.
Since the news has discovered that vista's UAC was designed to annoy people. (sick sense of humor i'd say)
despite what people say, UAC does not help security in any way. McAfee security center does 410% better job than uac ever will. (actually linux is more secure than vista)
I'm an advanced power user and i work in admin privilege settings daily so uac gets on my nerves and i have to turn it off after every windows update. ARRGH!!
Is there a way to create a safe program whitelist that will suppress the UAC prompts?
I am especially annoyed that vista was built basically to say- hey stupid! Fix me when you change me from defaults.
I wish there was a I'm not stupid version/setting in vista.
