This post details on UAC configuration, what’s changing in Windows 7, and what’s available today. Because, there’re a lot of people who don’t fully understand how to configure UAC as it exists in Windows Vista.
Always Notify Me: This is UAC configured the way you get it on Windows Vista today. This one should be very familiar.
Notify me only when programs try to make changes to my computer: This one is genuinely new for Windows 7, and essentially will auto-approve elevation when performing some actions to modify system state. I won’t get into the mechanics of exactly what we’re doing, because it’s neither final nor am I currently authoritative on all of the details behind the logic here. My goal here is to explain what you could do today, anyway.
