● The "Open" command from the EMS Explorer right-click menu has been removed. [24040]
● File corruption issues related to an Intel update to the CPU IPP libraries no longer occur. [24086]
● Changes were made to the SDE key unlock mechanism to accommodate processors that reflect battery life in CPU ID.
[24195]
● Improvements have been made to timing issues related to start up that resulted in blue screens. These issues occurred
rarely, but were serious in nature. [24212]
● When using HP Trim (which is an internal cloud sharing/collaborative file repository) file corruption issues no longer occur.

● The issue of "Double Fault (NO_MORE_IRP_STACK_LOCATIONS BSOD)" have been resolved. This problem occurred
because a Microsoft driver assumed that no more than three file-system drives are in use at the same time. New logic has
been implemented to correct the issue. [24477]
● Rare instances of computers failing to resume after hibernation have been addressed. [24571]
● When running the Shield on a computer that has recently updated to the latest version of McAfee Virus Scan 8.7 Patch 5,
McAfee Virus Scan 8.8 Patch 1, or McAfee HIPS 8.0 Patch 1, files can become corrupted.
The issue is that the McAfee driver is being injected below Dell Data Protection | Encryption in the filter stack. Microsoft
has confirmed that there is an problem in the automatic ordering of the drivers when mini-filters and legacy file system
filter drivers are present. Microsoft has also approved our approach of introducing a pass-through mini-filter driver at higher
altitude/class to resolve the issue. This issue is not specific to Dell and was reproduced at Microsoft using only the samples
from the Driver Development Kit. Other backup and encryption vendors affected by McAfee's patches are also using the
same approach to resolve the issue.
To resolve this issue, remove the McAfee software patches listed above, restart the computer, and install Dell Data
Protection | Encryption v7.2.3. [24085]
● Previously, when waking from a sleep state, a "No fixed storage is found" message was displayed in the local console under
the System Storage tab on some X4 and ACER platforms. This issue has been resolved. [24581]

● Under some circumstances, the local console "compliance status" displayed for the eSATA port may be different than the
actual status. To resolve the issue, reboot the computer.
● On some Dell platforms, the desktop background turns black after the computer wakes from a sleep state. To work around
this issue, go to display settings and reset the desktop background. [24574]
Technical Advisories v7.2.1
Encryption
● When using a desktop computer and attempting to block SD card ports by using the "Port: SD" policy, blocking SD ports
will not be successful. For desktop computers, the "Storage Class: External Drive Control" policy must be used to effectively
block SD ports. The use of the "Storage Class: External Drive Control" policy blocks access to all external storage devices
irrespective of what bus they are on. When using a laptop computer, SD ports can be blocked using the "Port: SD" policy.

● The F8 "discard the hibernation data" option MUST be used on the first system restart after software HCA decryption (using
the recovery tool/bundle) is performed on a system drive that contains a valid hibernation file. HCA maintains a drive state
value that identifies what drives are encrypted. Because of this, during hibernation resume, HCA attempts to decrypt data
that is read from the disk and encrypt data that is written to the disk (this transition in the hibernation file causes disk
corruption). Instructions: 1. Allow HCA decryption to complete. 2. During the first reboot after HCA decryption, before the
operating system loads, press F8 and select "discard the hibernation data". The user can now resume normal operation of
the computer.
● When using a computer equipped with a Hardware Crypto Accelerator, the Preboot Password Requirement dialog that is
displayed is misleading regarding Hardware Crypto Accelerator usage. The message will be changed in the next major release
to display: "A recent policy update requires the initial setup of the preboot authentication system. To enter the BIOS setup,
reboot and click F2 during the Dell splash screen. Go to the "Security" option and select Preboot Authentication > Set
System Password. Enter a password and exit the BIOS setup." [23205]
