I updated my BIOS with bitlocker on, worked fine last update but now it says my password is incorrect even tho I looked at it for errors. How to fix? Will installing old BIOS downgrade microcode?

    Updating the BIOS shouldn't affect Bitlocker or the operating system in any way. Hopefully you saved a Bitlocker recovery key to a flash drive or linked it to a Microsoft account to sign in with. Your best bet would probably be to check with Microsoft on Bitlocker password recovery (https://support.microsoft.com/en-us/help/4530477/windows-10-finding-your-bitlocker-recovery-key).

    If you're locked out of Windows by a Windows password, you can change or delete it using Hiren’s BootCD PE.

    On another PC, grab the Hiren’s BootCD PE.iso and install it on a USB flash drive using the ISO2USB.exe tool..Boot your PC from the USB flash drive..Then see the Resetting Windows Password instructions.
     
    Easy peasy..Works flawlessly for me.
     
    It don't know if it will work because of Bitlocker though..Can try it.

    It’s only got “tpm and pin” as protectors on the boot drive, oops. The software tpm choked somehow, or the os config didn’t like it. i know matter of fact the pin i enter is right. IDK how to fix the tpm. Might need to reinstall. At least the rest of my data is safe.
