I want to have a program (B) close automatically when I quit another program (A).

I have created a .bat file, and it looks like this:
start "" steam://run/220260
start /min "" "C:\Program Files (x86)\Orekaria\Gamers Window Relocator\GamersWindowRelocator" GamersWindowRelocator.exe
What I would like to do it have the "GamersWindowRelocator.exe" (B) quit automatically when I exit/quit the first program (steam://run/220260) (A), witch is a game.

Is this possible in CMD?
