Forum member RaZ0R put together a little tutorial to demonstrate how one would gain Administrator privileges on a Windows machine from within a limited user account.

In a few easy to understand steps, you can go from a limited account to power user in minutes.  This can be helpful if your administrator profile happens to be come corrupted, or if you just need to quickly get administrator access, for whatever reason.

Obviously, use this on computers that you own, on which you are permitted to have administrator access!
