With Vista you can type in a command into the Start search bar (such as “cmd.exe”) and then hit CTRL-SHIFT-ENTER to have it launch with Administrative privileges.
You then have to acknowledge the launch via UAC (you do have UAC turned on right). You can short-cut this with ALT-C for “Confirm”
Nice easy way to get Admin DOS shell.
Windows 7 changed the keyboard accelerator from ALT-C to ALT-Y (Yes)
I know it’s little, but it’s something my finger memory will need to deal with on a regular basis, swapping between the two environments
