In a tight spot with BitLocker on your Windows system?
For example wanting to do a hardware change(s) to your system?
Become IT dept independent!

Disable BitLocker, do your changes, and turn it back on.

Please note : You will need an admin shell – not God mode, just a ‘run as admin’ dos box.

1) In the shell type:

 manage-bde -protectors -disable C:

2) Do the changes.

3) Turn it back on:

 manage-bde -protectors -enable C:

Thats it. YMMV
This is also a decent resource:
