Personally, I’m a big fan of UAC (User Account Control) and the additional security it brings to the world of Windows. And one of the things I enjoy about Windows 7 is the fact that Microsoft tweaked a lot the number of UAC prompts, versus Windows Vista. If you want to know by how much, check out this very interesting benchmark. The Conclusion? In Windows 7 you have both good security and a more pleasant user experience.
