[rdp] Can RDP clients launch remote applications and not desktops

This is quite easily achievable.

  1. We need to allow any unlisted programs to start from RDP.
    1.1 Save the script below on your desktop, the extension must end with .reg.
Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Terminal Server\TSAppAllowList]
    "fDisabledAllowList"=dword:00000001


       1.2 Right click on the file and click Merge, Yes, Ok.

  1. Modifying our .rdp file.
    2.1 At the end of our file, add the following code:
remoteapplicationmode:i:1
remoteapplicationname:s:This will be the optional description of the app
remoteapplicationprogram:s:Relative or absolute path to the app
                           (Example: taskmgr or C:\Windows\system32\taskmgr.exe)
remoteapplicationcmdline:s:Here you'd put any optional application parameters


Or just use this one to make sure that it works:

remoteapplicationmode:i:1
remoteapplicationname:s:
remoteapplicationprogram:s:mspaint
remoteapplicationcmdline:s:

        2.2 Enter your username and password and connect.


    3. Now you can use your RemoteApp without any issues as if it was running on your local machine
