The main use for pythonw.exe is if you write a GUI program in Python (using e.g. TkInter, wxPython, etc) and you want it to be able to run it from an icon (desktop, start menu) without it opening a console window (running a console executable from an icon will open a console window).
In particular, IDLE runs in a pythonw process and it executes user code in a separate pythonw process and usually uses a socket for the connection.
