Windows 7 and I think Vista before it, does not actually have you run as an administrator despite what it says. For security reasons, it is considered very bad to always run as administrator because then any program you are using in your space will also have admin privileges, which means a virus or other malware you pick up on the Internet through your browser would have admin privileges. So it actually runs you as a regular user, but allows you easy and quick upgrading to admin (for example, right click on the icon and select "run as administrator"). Or, you could change a programs properties to always run as administrator. But, otherwise, all programs are run as a common user despite the fact that you are an administrator.
Those of us that are security conscious were VERY happy with this decision by Microsoft and it should help prevent a lot of problems.
