User Account Control is one of those Windows features that evokes a number of different responses from folks. Most people appreciate the enhanced security UAC offers, but we did hear complaints about the high number of UAC prompts in Windows Vista. This led some customers to turn off UAC, which concerns us from a security perspective. So in Windows 7, we've given a great deal of thought to how we marry enhanced security with ease-of-use. We have written extensively about the changes in UAC for Windows 7 on the Engineering Windows 7 blog (Post 1, Post 2, Post 3, Post 4).
Now, Technical Fellow Mark Russinovich weighs in on UAC with some great insight on the technology and some of our motivations around the decisions we have made. Check out Inside User Account Control now available online from TechNet Magazine.
