windows has nothing to do with the bios settings. if you want to reset the bios password read this

if you're talking about changing the windows user profile password, you can try using hiren's boot cd, booting the mini windows xp and using the tool to change the user password.

You probably don't deserve this. Anyone that uses this should only do so if they are acquiring a laptop for freezee.

Well, it used to be free, back when it was being tested.
I have an older version floating around somewhere.

Doesn't removing the CMOS battery for a good while and putting it back in fix that too?
I know it resets all user settings to default, BIOS password is just another user setting, correct?

removing bios battery does work sometimes, sometimes not. But if read about brute force BIOS attack, should be easy and simple as passwords are mostly easy

Windows has nothing to do with the BIOS, BIOS is what loads Windows.
To reset your BIOS you want to remove your CMOS battery from the motherboard of your computer

BIOS is NOT what loads "Windows"
BIOS (basic input/output system) is the program a personal computer's microprocessor uses to get the computer system started after you turn it on. It also manages data flow between the computer's operating system and attached devices such as the hard disk, video adapter, keyboard, mouse and printer.
After BIOS, BIOS runs POST
A power-on self-test (POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on.
If the computer passes POST, it will then boot up the system from whatever media you have set in BIOS.
So go shoot yourself in the foot thinking BIOS is what loads Windows
Furthermore directing at OP
There are several ways to bypass a BIOS password, the easiest being to remove it all together, this would either be removing the CMOS battery, or clearing CMOS via a jumper on the motherboard.
Complementary metal-oxide semiconductor, or CMOS, typically refers to a battery-powered memory chip in your computer that stores startup information. Your computer's basic input/output system (BIOS) uses this information when starting your computer.
If you clear CMOS, it removes the password.
Other than that you can check if their is a backdoor password that depending on the age and manufacturer of the motherboard may have included.
Other than that, there is also the possibility of Socially Engineering the owner that set the BIOS password

Like nrael said sometimes it works and sometimes it don't, it mainly depends on the hardware configuration of the system. There are different types of chips, so the usual old type of bios chip was a type of RAM. This meant that the chip was volatile. That is why when you took out the CMOS it would reset because it required power to retain the configuration information such as BIOS password.
Now some of the new hardware uses EEPROM in order to retain the configuration information even after power loss and the information can only be change via the BIOS system interface which may be protected by a password.
