For those of you who have pinned any program to your Windows 7 taskbar, you can hold down the Ctrl and Shift keys when clicking the icon and it will launch it with Administrator privileges.
I use this frequently when I need to run Visual Studio 2010 with Administrator privileges, but it will work with any program.
Now I just need someone to write a VS2010 Extension to relaunch VS2010 with Administrative privileges for the same Solution file. Maybe I have a new project on my hands...
