After upgrading my machine from Windows 10 to Windows 11 (Insider) i stumbled onto an issue with BitLocker witch was not enabled anymore on my machine.

I have compliance policies in Microsoft Endrpoint Manager (Intune) witch need`s BitLocker enabled to give the machines the “Compliant” stamp.

When trying to enable BitLocker we got the error message:

So a work-arround to fix this is to delete some registry entries from this location

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\FVE

In my system I deleted all marked entries and rebootet the machine.
After the reboot I could enable BitLocker as normal.
