The following method collected by my best friend and I think it may be useful when you come across lost Compaq password.
1. Turn on or reboot/restart the computer.
2. Tap the F10 key repeatedly once you see the Compaq logo until the recovery screen appears. On some models it may be the F11 key. This must be done before your operating system begins to load. If you see the Windows logo appear on screen, you'll have to restart and try again.
3. When the recovery screen appears, press "Next" and then "Yes" to perform a non-destructive recovery.
4. To perform a destructive recovery, click "Advanced" and then "Yes".
5. After the recovery is finished, the laptop will reboot. Ok, you can log in your laptop after Windows 7 password reset.
