The docs could add an example commandline to edit the per-user .ini: 

NT 6: notepad "%LOCALAPPDATA%\py.ini"
NT 5: notepad "%USERPROFILE%\Local Settings\Application Data\py.ini"

Editing the global .ini would be simpler if the launcher looked for it in FOLDERID_ProgramData (i.e. CSIDL_COMMON_APPDATA). In that case even a limited user could create it. For example:

NT 6: notepad "%ProgramData%\py.ini"
NT 5: notepad "%ALLUSERSPROFILE%\Application Data\py.ini"

The security on %ProgramData% grants full control to the creator of files and directories. It also allows all users to create, read and execute files and directories.
