Be the super user

If you're nervous of the consequences of disabling UAC, but want to avoid all the nagging prompts and keyboard shortcuts that leaving it enabled can entail, there's a better way. You can convince the operating system that you are actually the one true admin with a simple command.

To enable full administrative privileges with a normal Vista user account:

Open an administrative command prompt.

Type 'net user administrator activate:yes' and hit Enter.
