Can RDP clients launch remote applications and not desktops

Question

Can RDP clients launch a remote application and then only display that application (and not the desktop)? The application would appear fullscreen within the client and if the application were closed the session would end.

Answer 1

Using an RDP connection file you can set the alternate shell to be your application; the file syntax is like

alternate shell:s:c:\winnt\system32\notepad.exe

and you pass that as a command-line argument to mstsc.exe; this similar to chrissr's solution, but without affecting every RDP session you launch. A fuller summary of settings here.

Answer 2

"alternate shell" doesn't seem to work anymore in recent versions of Windows, RemoteApp is the way to go.

remoteapplicationmode:i:1
remoteapplicationname:s:Purpose of the app shown to user...
remoteapplicationprogram:s:C:\...\some.exe
remoteapplicationcmdline:s:

To get this to work under e.g. Windows 10 Professional, one needs to enable some policy:

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services]
"fAllowUnlistedRemotePrograms"=dword:00000001

Answer 3

This is called "seamless" mode. rdesktop, the RDP client for Unix, is capable of this. From the manpage:

   -A     Enable SeamlessRDP. In this mode, rdesktop creates a X11 window for each window on the server
          side.  This  mode  requires  the  SeamlessRDP  server side component, which is available from
          http://www.cendio.com/seamlessrdp/.  When using this option, you  should  specify  a  startup
          shell which launches the desired application through SeamlessRDP.

See mentioned Cendio website for more information.

Answer 4

Yes, you can change the default shell from Explorer.exe to a specific application.

In Regedit, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon. The current shell should be Explorer.exe. Change it to YourApp.exe. That will change the shell for all users who log on to the machine. If you only want to change it for a specific user, go to the same key in HKEY_CURRENT_USER instead.

Answer 5

This is called RemoteApp. To use it you need to install Terminal Services, which is now called Remote Desktop Services.

Answer 6

I think Citrix does that kind of thing. Though I'm not sure on specifics as I've only used it a couple of times. I think the one I used was called XenApp but I'm not sure if thats what you're after.

Answer 7

Another way is shown in this CodeProject article:

http://www.codeproject.com/KB/IP/tswindowclipper.aspx

The basic idea is to create a virutal channel that sends the windows position of the app(s) you want to show, then only render that part of the window on the client.

Answer 8

RDP will not do that natively.

As other answers have said -- you'll need to do some scripting and make policy changes as a kludge to make it hard for RDP logins to run anything but the intended application.

However, as of 2008, Microsoft has released application virtualization technology via Terminal Services that will allow you to do this seamlessly.

Answer 9

At least on 2008R2 if the accounts are only used for RDP and not for local logins then you can set this on a per-account basis. That should work for thin clients. If the accounts are also used on local desktops then this would also affect those logins.

In ADUsers&Computers, open the properties for the account and go to the Environment tab. On that tab, check "Start the following program at logon" and specify the path and executable for the program.
