Microsoft provided a new command-line switch, /ReflectDrivers, which are available only in the Windows 10 Anniversary Update. It allows drivers to be added to the operating system image during the setup and installation phase, via configuration file (*.inf). For more information about this new command-line switch and others, see: https://msdn.microsoft.com/en-gb/windows/hardware/commercialize/manufacture/desktop/windows-setup-command-line-options.

Upgrades are supported from the following operating systems, which are configured to use either a Basic Input/Output System (BIOS) or Unified Extensible Firmware Interface (UEFI) system, to the Windows 10 Anniversary Update:

  • Windows 7
  • Windows 8.0
  • Windows 8.1
  • Windows 10 (Released to World)
  • Windows 10 version 1511 (November Update)

  • DE 7.1 Patch 3 Hotfix 1148978 (build 7.13.604) or later must be in place before you start the upgrade to Windows 10 Anniversary Update.
  • Support for Opal upgrades is not available.
  • Download the Windows 10 ISO from the Microsoft Volume Licensing Service Center (VLSC) site.
    WARNING: The steps contained in this article do not work for the Windows 10 ISO from the public Microsoft Download Center.
  • You must complete the procedure in this article when upgrading to Windows 10 Anniversary Update.
    WARNING: If you perform the upgrade without first following the instructions outlined in this article, after the first system restart, Windows will fail to boot correctly and will display the following two options:
    • Troubleshoot the problem
    • Turn off your PC

      At this point, select the option Turn off your PC. When the computer is turned on again, Windows has rolled back to the previous operating system state, before the upgrade attempt.

Upgrade steps for DE 7.2.0 and DE 7.1 Patch 3 Hotfix 1148978

DE 7.2.0 drivers must still be updated to avoid upgrade issues that are caused by changes that were made to the Microsoft reflect drivers after the release of DE 7.2.0. 
  1. Download and extract the OSUpgradeDriverPackage_X.zip file in the Attachment section of this article.

    NOTE: For systems configured for Basic Input/Output System (BIOS), this method of upgrade is only supported if the operating system partition is labeled C:\ in Windows.
  2. From the extracted .zip file, copy the required folder to C:\Program Files\McAfee\Endpoint Encryption\OSUpgrade.

    • With DE 7.2.0 and later, you are overwriting existing files in the \OSUpgrade folder.
    • Use one of the following folders:
      • Win32 for a 32-bit image
      • Win64 for a 64-bit image
      • Win32Fips for a 32-bit image, with DE installed in FIPS mode
      • Win64Fips for a 64-bit image with, DE installed in FIPS mode
    • The following folder contains the following drivers and their configuration files:
      • Mfeccde.sys
      • MfeEpePc.sys
      • MfeEpeOpal.sys

        Although Opal drives are not currently supported with this process, MfeEpeOpal.sys must still be copied and no changes made to any file.
  3. From the administrator command line, locate the image and type the following:

    Setup.exe /ReflectDrivers "%programfiles%\McAfee\Endpoint Encryption\OSUpgrade"


    Setup.exe /ReflectDrivers "C:\Program Files\McAfee\Endpoint Encryption\OSUpgrade"
  4. Complete the Windows 10 setup procedure as required.
IMPORTANT: During the Windows upgrade process, Windows performs two system restarts. We strongly recommend that you allow these two restarts to occur. The system restarts are part of the upgrade process. You can opt to use the DE temporary autoboot feature to disable preboot during these restarts, to make the upgrade process simple.
