RemoteFX user experience is not enabled on a Windows 7 SP1-based virtual machine that is hosted by a Windows Server 2012-based computer

Symptoms

Consider the following scenario:
  • You install the Hyper-V role and Remote Desktop Session Host role on a computer that is running Windows Server 2012.
  • You create a Windows 7 Service Pack 1 (SP1)-based virtual machine on the computer.
  • You do not have the updates that are described in Microsoft Knowledge Base (KB) articles 2574819 and 2592687 installed on the virtual machine.
  • You enable the RemoteFX virtual graphics processing unit (vGPU) on the virtual machine.
  • You configure the computer to use Remote Desktop Connection Broker (RD Connection Broker) to provide access to the virtual machine for users.
  • You connect to the virtual machine from a Windows 8-based client computer by using RD Connection Broker.
In this scenario, the user experience that is improved by the Microsoft RemoteFX feature is not enabled on the virtual machine.

Notes
  • If you connect to the virtual machine directly, the RemoteFX user experience is enabled on the virtual machine.

Cause

This issue occurs because RemoteFX is optimized to only support local area network (LAN) connections in Windows 7 SP1. In other words, you have to use a LAN connection to establish a RemoteFX vGPU Remote Desktop Protocol (RDP) session to a Windows 7 SP1-based virtual machine.

The RemoteFX Network Auto-Detect feature is introduced in Windows 8 and Windows Server 2012 as a new feature. By default, the feature is enabled on a Windows 8-based or Windows Server 2012-based computer. When you start an RDP session from a Windows 8-based client computer, the "Detect connection quality automatically" setting is selected by default. Therefore, the session cannot be recognized as a RemoteFX vGPU RDP session by a Windows 7 SP1-based virtual machine.

Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    VersionProductMilestoneService branch
    6.2.920 0.16 xxxWindows Server 2012RTMGDR
    6.2.920 0.20 xxxWindows Server 2012RTMLDR

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2012" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components.
