How to reset various forgotten or lost passwords:
Windows XP Password
When we install Windows, it automatically creates an account “Administrator” and sets its password to blank. So if you have forgotten your user account password then try this:
Start system and when you see Windows Welcome screen / Login screen, press ctrl+alt+del keys twice and it’ll show Classic Login box. Now type “Administrator” (without quotes) in Username and leave Password field blank. Now press Enter and you should be able to log in Windows.
Now you can reset your account password from “Control Panel -> User Accounts”.
Same thing can be done using Safe Mode. In Safe Mode Windows will show this in-built Administrator account in Login screen. Safe mode is selected by rebooting your machine and Pressing F8 before the Windows boot screen appears.
