Sophos Central: How to decrypt the drive after encryption drive on Windows 7/10

  • This article will show you how to decrypt the drive after the drive has been encrypted using Sophos Central on Windows 10 and Windows 7.


  • After the drive on the machine is encrypted, we cannot arbitrarily decrypt the drive.
  • If we try to decode, the system will automatically re-encrypt the drive.
  • To decrypt the drive we need to contact the administrator to administer the encryption policy off on the computer or remove the computer from that encryption Policy.
  • To do that we have to log into Sophos Central with an account with Admin rights.
  • Click Devices and select the encrypted host name that we need to decrypt.
  • Clicking on the Policies tab, we will see that the Policies have been applied to the machine.
  • Click on the Policy we created to encrypt the machine, and the Policy edit panel will appear, select the POLICY ENFORCE tab and turn off the policy then click Save.
  • Next we will perform disk decoding.

For Windows 10

  • Open ThisPC > right click on the encrypted drive select Manage BitLocker > Select Turn Of BitLocker and Decrypt process will start.

For Windows 7

  • Click the Windows icon and enter the ‘bitlocker’ search box and select BitLocker Drive Encryption.
  • Next select Turn Of BitLocker to Decrypt drive.
