Enable the (Hidden) Administrator Account on Windows 7 or Vista

Many people familiar with prior versions of  Windows are curious what happened to

the built-in Administrator account that was always created by default. Does this account still exist, and how can you access it? 

The account is created in Windows 7 or Vista, but since it’s not enabled you can’t use it. If you are troubleshooting something that needs to run as administrator, you can enable it with a simple command. 

(Note: You really should not use this account for anything other than troubleshooting. In fact, you probably should not use it at all.)

<>Enable Built-in Administrator Account: 

First you’ll need to open a command prompt in administrator mode by right- clicking and choosing “Run as administrator” (or use the Ctrl+Shift+Enter shortcut from the search box) Now type the following command:net user administrator /active:yes 

• You should see a message that the command completed successfully. 
• Log out, and you’ll now see the Administrator account as a choice.(Note that the screenshots are from Vista, but this works on Windows 7) 
• You’ll note that there’s no password for this account, so if you want to leave it enabled you should change the password. 

<>Disable Built-in Administrator Account:

• Make sure you are logged on as your regular user account, and then open an administrator mode command prompt as above. 
• Type the following  command:net user administrator /active:no 

• The administrator account will now be disabled, and should not show up on the login screen anymore.
