Technical Advisories v8.15
Encryption
● If the CmgHiber.sys or CmgHiber.dat file is missing from C:\windows\system32\drivers on a computer that
hibernates, the computer will not resume. Ensure that disk cleaner and optimization tools do not delete these files.
[DDPC-6211]
● Policy updates are not received following a user security identifier (SID) change. [DDPC-6374]
● Encrypted user and common data on a computer with an HCA card is unrecoverable if the user clears HCA ownership, even
though the computer is not HCA-encrypted, because the user and common keys are wrapped in the GPE (HCA) key.
[DDPC-6505, DDPC-6535]
● On rare occasion, the Local Management Console becomes unresponsive. To work around this issue if it occurs, add the
following exclusion to the SDE Encryption Rules policy: -^3C:\Windows\Globalization [DDPC-6547]
● Command-line uninstallation with the Encryption Removal Agent parameter fails. To work around this issue, uninstall with the
master installer or by double-clicking the child installer executable file. Dell recommends storing a copy of the LSARecovery
file locally before running a scripted uninstallation with decryption. [DDPC-6568]
