Hi,
Thanks for contacting Fixya.com
This is bad as if you happen to be on a domain, you can contact your system administrator to change your password for you. If you're not on a domain and there are no other administrator accounts on your computer and you do not have a password reset disk, you'll need to reinstall Windows 7. Also before formatting reboot into safe mode - F8. Change log in screen to administrator, first try leaving the password blank, hit enter. See if this works.
To make sure this doesn't happen in the future, create a password reset disk - http://windows.microsoft.com/en-US [...] reset-disk
Let me know if you need any further information.
