Lost User Passwords. (Windows XP)
If you have lost or forgotten a user account password in Win XP, simply log in as the computer administrator, and go to control panel, user accounts. Here you will be able to reset the password for any of the systems user accounts.
Lost Administrator Password. (Windows XP)
Slightly more work needed if you lose or forget the Windows XP administrator password.
First reboot Windows XP in safe mode by re-starting the computer and pressing F8 repeated as the computer starts up. Then (in safe mode) click Start and then click Run. In the open box type "control userpasswords2" without the quotes - I have just used quotes to differentiate what you have to type.
You will now have access to all the user accounts, including the administrators account and will be able to reset the lost password.
Just click the administrators user account, and then click Reset Password.
You will need to add a new password in the New password and the Confirm new password boxes, and confirm by clicking OK.
All done, you have recovered the lost adminitrators password!

In some cases some people like to overwrite the entire disk before reformatting and reinstalling windows to prevent any old files from being recovered and/or to eliminate any possibility (rare) of malware still being on the hard drive after formatting and reinstalling windows . Any of the following will accomplish this.
