I used the following command in the console: bcdedit /set TESTSIGNING ON
This made bitlocker ask for my recovery key on every boot, even after i changed it to the original value.
In the screen on boot it says "... Otherwise restore the original BCD setting".
Thats what i did. Why doesnt bitlocker recognize that i restored the original setting?
I know i can probably resolve this issue with the manage-bde command (suspend), but it is disabled through group policy.
