The bios password is by no means a protective layer. Since it can be easily circumvented by removing the mainboard battery, we can only talk of protection at all, if you use it together with other measures, namely a TPM chip and a tpm-aware full disk encryption.

That said, the bios is not connected to windows. We cannot tell you where to change it unless you name your mainboard type. Normally, there will be a section named "security" where you can do that.

Hi! Like the previous member posted it is always going to depend on motherboard's brand. Your computer’s BIOS or UEFI firmware offers the ability to set lower-level passwords which allow you to restrict people from booting the computer, booting from removable devices, and changing BIOS or UEFI settings without your permission. You have 2 password options to be defined in BIOS and depending on how you configure the password, you'll will need the password to boot the computer or just to change BIOS settings. You'll find these passsword settings on the security tab on your BIOS.

Hope it helps

BIOS passwords of laptops are secure, as you can only remove those if you know the password, or when you forgot it, you need the help of the PC manufacturer, and you need to provide them with proof that you are the owner of the laptop, before they will help. Those passwords can't be reset simply by removing the BIOS battery.  This makes stolen laptops practically worthless to crooks.

On desktops BIOS passwords usually don't have the same level of security, as those PC's are stationary in controlled environments, it is less likely that they get stolen. So the manufacturers of those mainboards usually don't bother making those passwords as difficult to remove, those may be resetable by removing the BIOS battery. The same applies to HD's. 2.5" disks built for laptop use have higher built-in password security, while 3.5" desktop disks usually don't even have the option.

But as said above, those passwords are set within the PC's BIOS. There are usually also several levels of those passwords, for example one that only allows you to enter the BIOS if you know the PW, another that needs the PW in order to start booting, etc. While Windows 8.x and UEFI BIOS allows you to change BIOS settings from within Windows, it is possible that not all options are available there, so I'd always do the changes from within the BIOS directly, not Windows.

Active Protection takes the fight to cryptojacking

"Those passwords can't be reset simply by removing the BIOS battery." - not with any device, but with many.
rindiCommented:
Not with any modern laptops. It may have been possible on very ancient laptops, but those might just be able to run windows 9x, not Windows 8.1. Some very low budget current laptops might have other ways of resetting BIOS passwords, but even on those removing the CMOS battery won't help.
McKnifeCommented:
I would be careful with such general judgements. Surely, most modern will do, but all modern devices?
rindiCommented:
I haven't come across any modern laptop where you could disable the password with removing the CMOS battery, and with "modern", I mean something that has been built within the last 10 years and now.

But as I said that is different on desktops, there it may be possible, at least on some low budget consumer desktops. but even there, if the desktop is for business use that wouldn't be enough.
McKnifeCommented:
Ok, my last statement for this excursion: we have older laptops (Dells from 2007/2008) which run win8.1 at the moment and the battery can be removed to erase the bios password. I don't know how many there are out there, but I wouldn't be so sure that most modern devices do indeed prevent this attack.

I have no idea why instructions on how to set the windows password ( https://www.experts-exchange.com/questions/28698484/How-to-Set-BIOS-Password-on-Windows-8-1-8-to-Ensure-Security.html#a40891018 )should help here.
Younghv? Please explain.
Also why would https://www.experts-exchange.com/questions/28698484/How-to-Set-BIOS-Password-on-Windows-8-1-8-to-Ensure-Security.html#a40889026 not be a solution? It explains how to properly secure a laptop which is the objective after all. It tells him why his measure does not even need to be considered.
McKnifeCommented:
Younghv, the author hasn't indicated what he wants to protect and against what attack type, to begin with. If we assume, he would like to protect his data, then by no means at all, a BIOS password is enough, no matter what it takes to remove it, since removing the hard drive is already enough to get the data. Do you agree?

If he wanted to protect bios settings against unauthorized modification, then, and only then it is some protective measure, which can be overcome, but at least it is a small hurdle.

Tell me, what would normally be the reason to set a bios password?
And what would normally be meant when we write "protect a windows computer"?

The answers would be different. The bios pw does not protect the data. That was my point and that is why I feel my comment is correct and should be honored as well :-)
I don't feel like discussing this. So if you feel that one should "protect a windows computer" by setting a bios pw then please do go on in the closing process.
McKnifeCommented:
Ok, so your "best answer" selection indicates that the answer must be somewhere within Rindi's first comment. Let me see... he wrote "as said above, those passwords are set within the PC's BIOS" so he refers to other comment(s) having named the solution before - why are those not selected as answers? Just wondering.
McKnifeCommented:
Pedro's comment referred to mine. I would like to know why you exclude me.
McKnifeCommented:
The solution (at least after what you chose to select) is
1 it's inside the bios in the security section
2 it depends on your brand

Those were part of my comment. Your personal judgement of what is incorrect in my first sentence does not change that.

Good bye.
