Thank you. Bitlocker is indeed still active. It is, however, disabled. When
you turn Bitlocker off for an encypted drive, you gte the choice to decrypt
the drive or simply turn bitlocker off. Turning Bitlocker off leaves the
drive encrypted but with a password available in plain text - without a
passphrase. That way, you can just turn it on again quickly.
If you have a change in your boot configuration, you will be asked on boot
to enter the key. This will happen every time you reboot. You "tell"
Bitlocker that the change is authorised by turning it off for the drive and
then turning it on again.
In my case, I turned it off, but cannot turn it on again. Now I cannot
decrypt the drive, as the option to do that only occurs when you turn it off.
So I have an encrypted drive with a plain text password - no protection.
I can't turn Bitlocker on, because it says that my system is not configured
to use it. Clearly my system is configured to use it as I have the encrypted
Is there anybody out there who's an expert in this matter?
It is clarly a software bug as it shouldn't be possible for Bitlocker to be
operating and at the same time saying that it can't operate.
