How to Remove Windows XP Logon Password After Forgotten

Get stuck at Windows XP Welcome screen and can't bypass the logon password? How to log on to Windows XP if you forgot the administrator password? PCUnlocker is an amazing bootdisk that can help you remove Windows XP logon password, and unlock a disabled, locked or expired user account.

To get the software to work, you will need to make a PCUnlocker Live CD from another computer. Boot your locked Windows XP system from the Live CD and you can easily remove forgotten logon password in the Security Accounts Manager (SAM). These instructions are written assuming a bootable CD is being used, but are essentially the same for a bootable USB drive.

1Create A PCUnlocker Live CD

  1. Download the PCUnlocker software using an alternative computer. Once downloaded, extract the ISO file (pcunlocker.iso) from the ZIP file.
  2. Next download and install ISO2Disc, a freeware for making bootable CD or USB drive. Run the ISO2Disc program, click on Browse button to select the PCUnlocker ISO image.

2Change Boot Order in BIOS

  1. After you've created a PCUnlocker Live CD, put it in the CD drive of the locked Windows XP computer you want to remove the password for.
  2. Power on the computer and quickly press the key indicated in the POST screen (i.e. DELETE key, F2 key, F12 key) to enter BIOS Setup. The exact key depends on your computer – if you don't see the appropriate key displayed on your screen, consult your computer's manual.
  3. Once you're in the BIOS Setup, go to the Boot menu. Change the boot sequence and set your computer to boot from CD/DVD first.

3Remove Windows XP Logon Password

  1. The computer will then restart from PCUnlocker Live CD. After a while, you'll see the PCUnlocker program and it shows you a list of local accounts stored in the Security Accounts Manager (SAM).

    Reset Windows Password

  2. Choose a user and click Reset Password button, the program will unlock / remove your forgotten Windows XP logon password immediately.
  3. Now take out the Live CD. The next time you boot, Windows XP will load up on its own without asking for a password. If you're on a multi-user computer, the logon screen will still appear after starting Windows XP but when you click on the user that had the password removed, you will not be prompted for a password and will instead enter Windows automatically.

If you don't see your desired user on the Windows XP Welcome screen, press Ctrl+Alt+Del twice to display the classic logon dialog and you will be able to type both user name and password.
