On a XenDesktop VDI I see in HKLM:\System\CurrentControlSet\Control\Terminal Server\WinStations keys "Console" and "RDP-Tcp" as expected, but also a key "EH-Tcp" with a WdName value "Microsoft RDP 5.2". This is a Windows 7 machine. What is "EH-Tcp"?
And why is there no key "ICA-Tcp"? Does XenDesktop not use ICA?
