How to enable administrator account on Windows XP

In every installation of Windows XP, there is a built-in and defaut administrator user account named Administrator, which is equivalent to super user or root in Unix system. However, if you have set up another user account in Windows XP, the Administrator account will be hidden, cloaked and invisible in User Accounts or Computer Management.
To see the Administrator account, you have to boot the Windows in Safe Mode. However, you can modify the Windows’s registry so that the Administrator account will be shown at Windows XP’s Welcome screen for you to select, in the Control Panel’s User Accounts and in the local user lists in Computer Management.
  • Click on the Start Button.
  • Windows XP users click on Run.
  • Type “regedit” (without quotes) in the open field and press enter.
  • Navigate to HKEY_LOCAL_MACHINE\ Software\ Microsoft\ WindowsNT\ CurrentVersion\ Winlogon\ SpecialAccounts\ Userlist .
  • Right Click in the Work Area and create a new DWORD entry.
  • Name it as Administrator and change its value to 1.
  • Exit Registry Editor and Reboot/ Restart your computer to apply the changes.
Note: To launch User Accounts in Control Panel, you can go to Control Panel -> User Accounts, or click Start -> Run, and then type Control userpasswords and press Enter.
Once you unhide and reveal the Administrator account, you can change its picture or assign it a password or change the password. In addition, on the next boot to the Welcome screen, the Administrator account will be visible, along with all of the computer’s other user accounts.
