If you are the administrator of a Windows 7 computer, then you can change the administrator account on that computer. To do this, open the Start screen and type “cmd” and hit enter. Then type “net user” and hit enter. The “net user” command will show you a list of all the users on your computer. You will need to select one of the users to change their administrator account to. To do this, click on the name of the user you want to change their administrator account to and then click on the Change Account button.
