When a user launches a Remote Desktop Services or Terminal Services RemoteApp, a Remote Desktop session is created in which the application runs. Any subsequent RemoteApps that are launched from the same client before the session is logged off will run in the same session. Additionally, any notification area (system tray) icons that are launched by the user will also run in the same session.
When all active application windows and all user-launched notification area icons are closed, the session remains active for 20 more seconds. This allows time for the user to launch another application, and for applications to display final messages or perform other closing tasks. If another application or system tray icon is not launched within that time, the RDP session is disconnected.
Leaving the session in a disconnected state allows subsequent RemoteApps to launch much more quickly. When a new RemoteApp is launched the session is simply reconnected instead of incurring the overhead of starting a new one.
