I believe it would be in the best interest of your software product and clients if you were to hide the command prompt for the batch file that launches the signage controller and player.
This can be achieved easily by using a shorcut.lnk in the startup directory instead of directly placing the batch file in the startup directory but linking it to the program files where the software is actually located. You can add a handle to the say, 'signagecontroller.lnk' to run minimized start /min myfile.bat or cmd.exe /c start /min myfile.bat ^& exit or something along those lines.
Please take this into consideration as I was unable to do this myself due to the fact every time signage launches it propagates itself back into the startup folder undoing all of my work and writing over any previous files.
This can also be achieved running a vbs script. But you guys are the programmers I'm sure you can figure it out. With this command prompt up for even a few seconds it exposes the directory and file structure of the signage player. Which to clients may not be a good thing in certain instances.
