This area is a bit messy. There is a difference between: going to the
command line and typing "myscript.py"; and double-clicking on a file in
Explorer.

The former uses the result of merging the assoc/ftype registry keys:

   HKEY_CURRENT_USER\Software\Classes\Python.File\shell\open\command

   HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Python.File\shell\open\command


while the latter uses the Explorer registry keys at:


HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.py\UserChoice


Initially, I suppose, the two are in sync. But presumably they can get
out of sync, especially if you move backwards and forwards between
associations. I haven't bothered fishing around in the Shell API but I
presume that you can reconcile the two -- or just edit the registry,
obviously.
