(3) Open the "User Account" in the "control panel", and you will see your user account, with the words "restricted account" next to it ".

(4) Click Open your account and then click "Change Account type ". In the displayed window, click the select button for "Computer Administrator" and then click "Change Account type" to confirm and exit. Now you can do what you want to do.
