How to organize remote control of the program?

Question

RDP

Is it possible to organize remote control of the program through Remoteapp? That is, make sure that the program window opens on the server, and the user sees exactly this window through Remoteapp (and can interact with it), and not the one that opens in a new session.
In this case, simply logging in through the remote desktop is not a solution, since the user should only have access to the program window.
UPD: I will give an example. The program window is constantly open on the server, for example, with a stopwatch leading the countdown. It is necessary that the user from the client computer can open exactly this window and see how much time has passed since the beginning of the countdown. At the same time, access to the desktop, the file structure of the server, etc. the user should not have - only to the program window.
PS The server is running Windows server 2008 r2

Answer 1

Standard MS TSC allows you to specify which application to run on the server. Instead of explorer, specify your application, and it will be the default shell for the user.
You can register the shell in the user's registry. It is possible by politicians to forbid it to open the explorer.
