YellowKey reportedly works in Windows 11, Windows Server 2022 and 2025, but not in Windows 10.

Does test mode unlock without the key?!? So it's just "encrypted" with a generic key, and the unlock key is for authentication? That sounds insane, even for microsoft.

    this works because the bitlocker key is stored in the TPM of the mainboard on the computer.
    That is neccessary for the computer to be able to boot without entering your bitlocker password. you can configure it differently, but that is not default or super obvious to do.

    It always struck me as...poor...to not require a password for decryption. If you require zero knowlege from me, that means a stolen has everything inside needed to decrypt all the data.

    And well, lookie there at the article!
