Windows – How to diagnose and fix Starting Bitlocker “Access Denied” message
bitlockerwindows 10
I've been trying to get my C: drive to use BitLocker, but it fails at some initializing step.
Is there a log or some other method that will explain the issue?
I've searched event logs etc.

Are you enabled BitLocker via RDP? If yes, please enable the following group policy:
Computer Configuration > Administrative Templates > System > Removable Storage Access > All Removable Storage > Allow direct access in remote sessions
I have the issue since Windows 8 and after some trial & error I figured out, that the running Taskmanager (Taskmgr.exe) blocks the eject of external HDDs. My guess is, that it is blocked because of the new disk IO graphs. I've already reported it, but since you still get it in Windows 10, the issue is still not solved.

If no, try to enable it as an Administrator.
