The Start button for the remote Windows desktop is in the lower left corner. If you have access to the Windows desktop and the window is not maximized, you can maximize it or scroll to the lower left corner to see the Start button.
If you are running a Windows workstation operating system, when the remote Windows desktop is full screen, the name of the Remote Client server appears in a Windows title bar at the top center with several buttons. If the pushpin to the left of the name is selected, then the title bar remains displayed. If it is not selected, the title bar automatically hides until you move your cursor to the top of the screen. (This is similar to what happens when auto-hide is selected on the Windows Taskbar and Start Menu Properties dialog.)
You can size the remote window so that you can see both your own local desktop and the remote desktop at the same time. When the remote window is less than full size, the title bar is displayed along the top of the window, along with the standard buttons for minimizing, maximizing/restoring, or closing the window. You can also use ALT+TAB or the Windows task bar to switch back and forth between desktops. The remote Windows desktop will appear as one application on the task bar, even though it may be running several programs. On a two monitor workstation, the local desktop may be on one monitor and the remote desktop may be shown either full-screen (maximized) or in a reduced size on the other monitor.
When you are on the Windows desktop, you have access to the same functions as if you were sitting at the server. From a DeltaV workstation, you can access the server through a remote session and have copies of, for instance, Control Studio open on both your local desktop and the remote desktop.
