Presumably this is the BIOS password not Windows (they are easy to clear)

See these links.

Try a default backdoor password for your BIOS manufacturer.

Beware making lots of guesses in case you get locked out permanently (unless you already have and it's not counting)

Try taking out the CMOS battery, but this may not work on many models.
