Hi,
I'm trying to open a virtual channel in my remote desktop-session. I'm calling the WTSVirtualChannelOpen-function of the WtsApi32.dll.
I already succeed to open and use the virtual channel, but since the windows-update 1903 the open-function failes with the error-code 50 (ERROR_NOT_SUPPORTED).
The client and terminal are both running windows 10 with the 1903-update.
I tried to check the Permission-Settings for Remote Desktop Services Connections, but I don't know how.
Other References said it moved to the Group-Policies, but I can't find it there.
I also tried to use the newer VirtualChannelOpenEx-function, but same result. The OpenServer- and EnumerateSessions-function are working fine.
So I'm searching for this Settings:

Thank you for your help,
Nils G.
