Resetting or recovering a forgotten BIOS/CMOS password can be a tough nut to crack as usually it requires opening the case and sorting BIOS battery. If you are able to boot into Windows, free utility CMOS De-Animator lets you do this without going through the manual procedure using just a single button click from Windows.

CMOS De-Animator basically clears the BIOS RAM, by smartly invalidating the CMOS verification checksum which results in resetting of all BIOS settings to default including the stored BIOS passwords on reboot.
