AFAIK, "stty onlret" will never work on Windows, as long as you use
the standard system shell.  You can ignore the fact that you have some
stty.exe, it won't do what you want, because that functionality is
simply not supported.

Please explain why you need that command, maybe there's an equivalent
solution.
