Same program, linked in different ways. See below.

Programs linked for the "console" subsystem (aka "character-mode
applications") have to be connected to a console window. If they're
not, Windows creates one for them.
(I'm pretty sure this is done by the loader and not the C runtime).

The "windows" subsystem.

A linker option, usually (/subsystem)
A console program may use the Windows API to disconnect from the
console, or create a window, and a window program may use the API
to create a console if it needs one (a version of pythonw that did this
if/when the application prints to sys.stderr would be quite useful, btw)
