I'm sorry but I am a little confused. Your title mentions BIOS password but your message indicates this is a forgotten Windows logon password? A BIOS password would prevent the machine from even reaching the Windows logon screen. Can you clarify which password you have fogotten?
Also we need to know what Operating System you are running-Windows 10 or Windows 8, Windows 7?
To make it easier-just post the full Model of the machine> How To Find Model/Product Number
