    I have a laptop with both the Intel and nVIDIA GPUs. If I enable Bitlocker and reboot after a GPU switch which is done by a button on the side, Bitlocker prompts me for my password again since it thinks now I have new hardware. This is getting tiring, can I have it not prompt me for a new password upon detection of a hardware change?

    You can 'suspend' bitlocker and it doesn't ask for a password for the next boot?

    Powershell:
    Suspend-BitLocker C:
    Suspend-BitLocker C: 10 (suspend for next 10 reboots)

    Cmd:
    manage-bde -protectors -disable C:

    Or you could go buy a Yubikey Neo or Yubikey 4 (standard), configure the device with a 'static' password and press the button on the key to make it type the password for you :)

    Another thing is to enable Bitlocker not to ask for password on the system from both GPUs(in Intel and in Nvidia).

    So how do you enable the BitLocker not to ask for password from the GPU's?

    I mean when you switch to both GPUs make sure you tick the box in 'automatically unlock on this PC' under 'More Option' . Whenever you are now switching GPU it will recognize it.
