@minime2k9 I’m curious if you have a write up on this method? I’ve never seen it before and would be interested in giving it a try
@Columbuscop2290 - Never actually written it up properly, the hardest part is creating a Windows2go usb, though this is a pretty good write up:

I think you do need a copy of Windows 10 Pro as opposed to home to be able to do this.
Once you have a machine booted, its basically just entering the manage-bde command. This will give you the recovery key for the mounted drive. It only works where a password is not required (unless you have the password too).
If you think about it logically, we are still running a completely legitimate version of Windows (i.e. Secure boot compliant) and therefore the TPM data will be available to us.
I used this technique first when I managed to erase a partition from a bitlocker encrypted disk (on a non-evidence device!!)
