The built-in Administrator account is a powerful one as it has complete privileges to do anything on the computer and, in Windows 7, it is not subject to UAC like other accounts (even those with administrative privileges). Normally, you can do whatever you need to do with a regular administrative account (which you will create when you install Windows 7). But the built-in Administrator account is still there – it’s just disabled by default for better security.

Here’s how to enable it: Open an elevated command prompt and type net user administrator /active:yes and press Enter. Now you will see the Administrator icon on the logon screen. You can also enable it through Local Users and Groups in Windows 7 Pro, Ultimate and Enterprise editions. If you enable the built-in administrator account, be sure to create a strong password for it. To do this, log on with the account, and in Control Panel, click the User Accounts icon and click “Create a password for your account.” Important: Do not leave the Administrator account without a password.
