This is almost moot because Windows hides file extensions by default and has done so since like Windows 95. So the user has to enable showing file extensions for known file types. You might as well name the file document.doc.exe

If you are pro user, you will notice the extra extension that shouldnt be there, if you are basic user, you dont care about extensions and try to run everything anyway.
