Took me a few hours to figure this out, figured I’d pass it along. Forgive formatting, I’m on mobile.

      It means the drive isn’t fully encrypted or the encryption is easy to bypass. That defeats the purpose of encrypting your drive.

      If you can get to a login screen, you’ve compromised the device.

        That’s not what it means.

        Bit locker is encryption at-rest. Logging in with an admin account means the system is no longer “at rest”. The admin is fully authorized to be operating that system.

          Any system without network unlock usually requires a TPM PIN/PW every reboot. Your instructions (when read a certain way) imply that the command also bypasses the encryption without fetching a recovery key from the TPM or DC.

          My home network (ISC DHCPD) behaves this way - either I type the TPM key or I type the 25-char key.
