You can let the program start when Windows starts by putting a shortcut in your "Startup" folder, or you can make a shortcut on your desktop so you can start it manually.
As you can see, the screen is very graphic, so you'll want to minimize it after you have tweaked it to your liking and you're satisfied that it is running properly.
To do this, find the TSC icon in your system tray:
The java application that displays the client window uses 10 - 20% of your available CPU resources, so it's a good idea to minimize the client to the tray.
Right click on the icon and select "Hide". When you want to see the screen again, repeat the process and select "Show".
