Nice, it's an elegant and easy solution to the problem. I like to get a
quite similar solution into the core but I propose a slightly different
Like your launcher.c, spam.exe looks for spam.py. It additionally looks
for spam.pyw first giving .pyw files a higher priority.
The first line of the file is read and parsed. The line must start with
a shebang (#!). Contrary to your script it doesn't look for a complete

from the registry (first HKCU, then HKLM). At last the script is
executed with the Python binary: python.exe for .py and pythonw.exe for
.pyw. The working directory is the absolute path of spam.exe. This way
we neither have to change the paths for Windows scripts nor quote the
