Just a real quick post to say that I noticed my desktop PC at home running Windows 7 had an optional update listed for Remote Desktop Protocol 8, the version included in Windows 8 and Windows Server 2012 natively.
The update is available for Windows 7 and Windows Server 2008 R2 with SP1.
The KB article for the changes and improvements in the protocol version at available at http://support.microsoft.com/kb/2592687.
The ky features appear to be support for VoIP applications via RemoteFX, Improved SSO for RDS Web Access, RemoteApp Reconnection. It’s also worth noting that Shadowing (Remote Control) of RDS sessions and Aero Glass Remoting are now deprecated, so if you are using Shared Session Virtualization as a VDI infrastructure, you might what to think about testing this update first if your users like their Desktop Experience RDS sessions.
