Make sure you only forget your login account password and your system will still boot normally. In addition, you must have the Windows XP bootable installation CD and Windows XP CD Key installed.
Perform password recovery
- Insert the Windows XP installation CD into the CD-ROM drive and boot your system.
- When the system asks you to press any key to boot from the CD, press Enter.
- You have to wait until the operating system has finished preparing the installation, then press ENTER to enter the Windows installation process.
- Press F8 when the Licensing Agreement appears.
- At the next screen, select 'Repair' (Repair) to the operating system. Use the up and down arrow keys to select the correct operating system on the hard disk that you need to fix - here is the operating system that you forgot your password.
- Repair process starts running. The Windows Installer will check your hard disk and copy the files. This process takes at least a few minutes depending on your system speed.
- After the copying process the system will restart once. During the boot process this time you cannot press any key and have to wait until the Windows installer starts to appear, this time with the inherent graphical interface of Windows XP.
- Now you have to pay attention to the bottom left hand corner of the installation screen when you see the Installing Devices text, and immediately press SHIFT + F10. A DOS-style text input window appears and you type in the command NUSRMGR.CPL and press ENTER.
- What will you get? You will access the User Accounts of Control Panel and here you can change your password in a very simple way. If you do not want to enter the password during the login process, at the code input window above, type control userpasswords2 then select not to ask for the password when logging in.
- Complete any process you close the window and continue with the simple installation process in a moment.
- What are your results? You will have an almost new operating system and login with a new password. Everything you have remains the same.
Note that in any case, you must not exit the operating system installation process until you have finished running, otherwise everything you have done will be a success.
