AFAIK, Python doesn't set environment variables in Windows. To change
the environment variable, you go to Control Panel > System > Advanced
> Environment Variables > System Variables > In "Path" entry, add
Python's installation directory to the end of it (remember to separate
it from other directories with semicolons ;

Alternatively, you can cd your way through python's directory and
always feed absolute path to python.exe, very tiresome, but doesn't
require you to add the environment variable.
