That's what I did:

   ls -l f:/ProgramFiler/Python35/python*.exe
   -rwxr-xr-x 1 XX Administratorer 37664 May 31 04:18 f:/ProgramFiler/Python35/python.exe
   -rwxr-xr-x 1 XX Administratorer 37664 May 31 04:18 f:/ProgramFiler/Python35/python3.exe
   -rwxr-xr-x 1 XX Administratorer 37664 May 31 04:18 f:/ProgramFiler/Python35/pythonw.exe

They all depends on:
  f:\ProgramFiler\Python35\python35.dll

The one and only python35.dll on this box. And also on PATH.

I took Ben Finney's advice to heart. From:
   http://code.activestate.com/lists/python-list/684547/

   Calling ‘python’ is now ambiguous, and with Python 2 slipping inexorably
   into the past, increasingly the ‘python’ command is the wrong choice for
   code that we want to survive in the future.

   I am seeing a growing call, with which I agree, to recommend explicitly
   calling ‘python2’ or ‘python3’ as commands.

That's why I made that copy; even if some of you find that strange on Windows.
I'll investigate is there's an issue with the Registry later.
