Last Modified:  1/3/2018


McAfee Drive Encryption (DE) 7.2.1, 7.2.0

For details of DE supported environments, see KB79422.


When the Autoboot policy is set to use the Trusted Platform Module (TPM), with the option If Available enabled, the DE Pre-Boot Authentication (PBA) unexpectedly displays, and asks a user to log in. 

NOTE: If the TPM policy is set to Never, Autoboot functions as expected.

MfeEep.log records the following error:
INFO SystemAutoboot Autoboot successfully enabled using TPM.

On the target system, the hardware does not support TPM.


This issue is resolved in DE 7.2.2 (build, which is available on the Product Downloads site.

Set the Autoboot policy to Never when using TPM, unless the system supports TPM.
