    Where in the BIOS does MS store the Win10 key


    I have had my BIOS locked with a password ever since I started testing Windows 10 Builds.
    I have not had to enter the password and have updated to the latest CB build. How does MS do this?
    or if it can do this How?
    I run a ASUS P9X79 LE motherboard.

    This is not new. Bios embedded keys were introduced in Window 8. They are hard coded into the bios (like a permanent ROM) and even a bios firmware update would not affect it.

    You do not have a Windows key in your BIOS. Only OEM boards have that.

    MS does not update BIOS with a Win10 key.
    The "Win10 license" is saved on a Microsoft Activation Server, for that PC/device.

    Here are some tutorials that might help:

    Thanks for the info.
    So what is it that MS uses to differentiate one VM from another?

    There are various details about a hardware computer or virtual machine that are unique and can uniquely identify it. I doubt that the details have been published.

    As far as i know each unique VM would be considered a "different device" on the MS Activation Server.
    Others may know for sure, and correct me if i'm wrong.

    That's news to me.
    Win 7 and earlier use a COA sticker for the license.
    Win 8 and later don't have a COA sticker, and use the key in the bios.
