Suddenly being locked out of your computer and all of its valuable information can be a true emergency, especially if you rely on your computer for work. If you do not have a password backup disk available, you will need to manually reset your administrative password to gain access to your computer. If a manual reset does not work for your computer, you will need to contact Microsoft Windows Support.
Start your computer with your Windows XP CD in your CD-ROM disk player.
Press any key to boot. Wait for Setup to inspect the system and load files.
Press "Enter to Setup Windows Now" at the "Welcome to Setup" screen.
Press "F8" to accept the licensing agreement.
Select your XP installation and press "R" to begin the repair process. Wait for Setup to check disks and copy files. This could take several minutes. Your system will automatically reboot. You do not need to "Hit any key to reboot from CD" again.
Press the "Shift" and "F10" keys when you see the "Installing Devices" progress bar in the lower left-hand area of your screen.
Type "NUSRMGR.CPL" without the quotation marks at the command prompt.
Click on the "User" you wish to edit. Click on "Change password." Change the password. Exit out of the "Control Panel" and the "Command Prompt" screen. Continue with Repair until repairs are complete.
Log on to your computer using your new password.
You must allow the repairs to complete before attempting to use your new password.
