September 2017 servicing release for Microsoft Desktop Optimization Pack

This article describes the contents of the September 2017 servicing release for Microsoft Desktop Optimization Pack (MDOP). This servicing release contains the latest fixes for the Microsoft Application Virtualization (App-V) 5.1 RTM Client and Remote Desktop Services (RDS), Microsoft BitLocker Administration and Monitoring (MBAM) 2.5 Service Pack 1 (SP1), and Microsoft User Experience Virtualization (UE-V) 2.1 Service Pack 1 (SP1).

Notes

• The App-V and UE-V Clients are "in-box" starting with the Windows 10 Anniversary Edition (Version 1607). The "in-box" App-V client continues to use the App-V 5.1 Server.
• Fixes that are delivered to the "out-of-box" versions of App-V and UE-V are first delivered for the "in-box" versions of App-V and UE-V in the monthly Windows 10 cumulative updates.
• We recommend that you test fixes before you deploy them in a production environment. Because the builds are cumulative, each new servicing release contains all the fixes (including security fixes) that were included in the previous update package. We recommend that you apply the latest servicing release.

Registry information

This servicing release includes update installers for App-V 5.1 RTM.

For App-V, the original client installation file contains installers for both x86-based and x64-based architectures. Running the .exe file automatically deploys the correct client. However, if the original client was deployed by extracting and using the architecture-specific .msi file, you must apply the associated .msp file to ensure a successful update. To extract the associated .msp file, run the following command:

AppV5.1RTM_Client_KB4041137.exe /LAYOUT

Important If you try to apply this update by running the AppV5.1RTM_Client_KB4041137.exe file instead of the (extracted) associated .msp file, you may receive the following error message:
