py.exe or pyw.exe come with the Python launcher on Windows and work out 
which version of the interpreter to use.

https://www.python.org/dev/peps/pep-0397/
https://docs.python.org/3/using/windows.html#python-launcher-for-windows

I think it was first installed with Python 3.3.  It's available here 
https://bitbucket.org/vinay.sajip/pylauncher if you're on an older version.
