Remote Desktop clients (mstsc.exe)


RDP 8.1 updates for Windows 7

These fixes update the Remote Desktop Services server-side roles and components that are built around Remote Desktop Protocol (RDP) 8.1. However, although updates are performed on the on the server-side infrastructure, the Remote Desktop Clients are often left untouched. This can cause performance and reliability issues. By default, older clients such as Windows 7 Service Pack 1 (SP1) are restricted to RDP 7.1 and do not provide the new features and improvements that are available in RDP 8.1. Therefore, we have released the RDP 8.1 client for Windows 7 to provide significant performance and reliability improvements when these clients are connected to RDS 2012 R2 environments. To enable RDP 8.1 on Windows 7, follow these steps:

  1. Verify which version of RDP you're using. To do this, start the Remote Desktop Connection client program (mstsc.exe), click the small Remote Desktop icon in the top-left corner of the application dialog box, and then select About. Verify that the "About" message indicates “Remote Desktop Protocol 8.1 supported.”

    RDP 8.1 Supported

  2. If the "About" message indicates "Remote Desktop Protocol 7.1 supported," install the following updates for RDP 8.1:

    2574819: An update is available that adds support for DTLS in Windows 7 SP1 and Windows Server 2008 R2 SP1

    2857650: Update that improves the RemoteApp and Desktop Connections features is available for Windows 7

    2830477: Update for RemoteApp and Desktop Connections feature is available for Windows

    2913751: Smart card redirection in remote sessions fails in a Windows 7 SP1-based RDP 8.1 client

    2923545: Update for RDP 8.1 is available for Windows 7 SP1.
  3. Install any outstanding Windows updates.
