The default value of the above registry key is only used if Python can't calculate the default sys.path based on searching for "os.py", the landmark module in the standard library. This can happen sometimes when Python is embedded or run from a symlink. The default value of each subkey of "[HKCU|HKLM]\Software\Python\PythonCore\<version>\PythonPath", on the other hand, usually does extend sys.path. Except that running Python with the -E or -I command-line options (both supported by Python 3.4) makes the interpreter ignore PYTHON* environment variables, including PYTHONPATH, as well as registry settings such as subkeys of "PythonPath". Even with the -E or -I command-line options, .pth files in the system site-packages are still processed. A .pth file can be used to extend sys.path as long as the site module is imported, i.e. as long as the -S command-line option isn't used. One difference, however, is that directories in .pth files are appended to sys.path and thus do not override the standard library. -- https://mail.python.org/mailman/listinfo/python-list
