Enable the (Hidden) Administrator Account on Windows 7 or Vista June 13, 2010

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 shouldn’t use this account for anything other than troubleshooting. In fact, you probably shouldn’t 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 shouldn’t show up on the login screen anymore.

GREAT TIPS!
Will help someone who forgot Windows password.
Here are also some trick that might help!
XP:
1 >> Log into safe mode
2 >> Log in as the computer Administrator, “Administrator” for the username
3 >> Leave the password blank
4 >> Control panel and change the password for your account

If you don’t want to change the password:

1 > Get a program called Ophcrack
2 >> Download the liveCD (ISO)
3 >> Burn the ISO to a CD using an ISO burner
4 >> The Live CD’s come with the free rainbow tables, so you might need to download other tables (cost money)
4 >> Bootup from the CD
5 >> Crack the SAM and System file

Or try some Windows password reset tool: http://search.yahoo.com/search;_ylt=AukdbPxVQ4p3R2h1Qm2QleSbvZx4?vc=&fp_ip=cn&p=windows+password+reset+standard&toggle=1&cop=mss&ei=UTF-8&fr=yfp-t-701
