Full disk Encryption error: your computer is already encrypted by Bitlocker

Hi there,

I have a problem while installing Full Disk Encryption,
Eset tells me that the computer is already encrypted by Bitlocker but it is not. I tried encrypting the pc bitlocker then disabling it but I still get this error message.

I don't know what to do, I couldn't find a topic about it.



Bonjour à tous,

J'ai un problème lors de l'installation de Full Disk Encryption,
Eset m'indique que l'ordinateur est déjà chiffré par Bitlocker mais ce n'est pas le cas. J'ai essayé de chiffrer le pc bitlocker puis le désactiver mais j'ai toujours ce message d'erreur.

Je ne sais pas quoi faire, je n'ai pas trouvé de topic à ce propos.

Hi @Heterz,

May I ask you to do the following for me just to confirm that BitLocker is indeed disabled on your machine:

  1. Open an Elevated Command Prompt
  2. Enter 'manage-bde -status'
  3. Send us a screenshot of the output please?

If we confirm that BitLocker is in fact 100% decrypted, we will need to request additional logging (https://support.eset.com/en/kb7123-eset-encryption-diagnostics-tool) and support case to be submitted to your local ESET Support Office via the following link: https://www.eset.com/int/support/contact/

Thank you,

Indeed BitLocker was activated without my asking...

It turns out that when installing windows bitlocker encrypts the main hard drive without being asked, and in the control panel it is not marked as activated... Thanks Microsoft again.

Thank you for your answer, the FullDiskEncryption program is working now.

Hi @Heterz,

Thank you for letting us know, I suspect Bitlocker automatically encrypted your main HDD for the following reason as stated on one of their articles:

"BitLocker automatic device encryption uses BitLocker drive encryption technology to automatically encrypt internal drives after the user completes the Out Of Box Experience (OOBE) on Modern Standby or HSTI-compliant hardware."

Thank you.
