When is this true?

Um, that's exactly how it works. There is a value in the PE 
header which determines this. The corresponding linker flag is 
/SUBSYSTEM:WINDOWS for a GUI program or /SUBSYSTEM:CONSOLE for a 
console program.

The flag specifies that you want to run a console application, 
but want to suppress its console window.
