Hot fix HF2 addresses the following issues:
- Some UEFI systems using non-U.S. keyboards do not boot correctly following encryption, such as Dell Latitude 7400 or Dell Precision 5540 systems. 
- Non-U.S. keyboards no longer work at preboot authentication on HP systems with BIOS firmware. 
- After upgrading Symantec Endpoint Encryption Management Server, Symantec Endpoint Encryption clients are intermittently unable to communicate with the Management Server. 
- When a user logs into Windows using a PIV card and is registered, the next time the user restarts the computer, the user is prompted for registration again through the PIV card.
