It can be enabled in Windows 7/8/8.1 by some tools.
When I use RemoteApp tool in Windows 10 PRO, and create rdp file with a valid configuration, the client can't run rdp file. Login window appears but when I login, nothing is happening (I am logging in with my laptop in same network, its Windows 10 PRO too, remote desktop woks fine).
I can see succesfull login in server's event viewer. So it's not a network issue, its not an account issue. I think something is different in Windows 10 about RemoteApp.
Anyone have ideas?
