If you are using XP Home, boot to safe mode (using F8) and enter the
Administrator account with a blank password (provided you did not change
it), and reset your personal logon. If you are using XP Pro, at the
logon/welcome screen hit <ALT><CTL><DELETE> twice and change the logon to
"Administrator" and enter your password to boot to the Admin account, here
again you can reset personal logon.
