After decryption, you cannot manually remove EEPC/DE from the client, and you see the following error:

Error: Machine still ACTIVE


After decrypting the system, use the following steps to modify the registry to allow EEPC/DE to be removed:

CAUTION: This article contains information about opening or modifying the registry.
  • The following information is intended for System Administrators. Registry modifications are irreversible and could cause system failure if done incorrectly.
  • Before proceeding, Technical Support strongly recommends that you back up your registry and understand the restore process. For more information, see: http://support.microsoft.com/kb/256986.
  • Do not run a REG file that is not confirmed to be a genuine registry import file.
  1. Click Start, Run, type regedit, then click OK.
  2. Verify the system is decrypted and not active. Navigate to the following location and verify the drive(s) are decrypted:

    64-bit (Win x64) supported systems:
    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\McAfee EndPoint Encryption\MfeEpePC\Status\CryptState

    32-bit (Win x86 ) supported systems:
    HKEY_LOCAL_MACHINE\Software\McAfee Endpoint Encryption\MfeEpe\Status\CryptState

    NOTE: This String Value should reflect as Volume=C:,State=Decrypted. The same applies if additional drive letters were encrypted.
  3. Navigate to the following location and set the system state to deactivated by setting the Activated string value to No.

    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\McAfee EndPoint Encryption\MfeEpePC\Activated

    NOTE:  If the value is already set to No, do not change this or you may still see the preboot authentication screen after removing EEPC and EEADMIN. 
  4. Save your changes and close the registry editor.
  5. Run the uninstall again to remove EEPC.
