It is a bit more difficult on Windows:

@rem Put this file (ediff.cmd) in your PATH.
@rem (Created by Setup Helper at Tue Apr 03 20:48:56 2007)
@rem -----------------------------
@rem Starts Emacs ediff (through gnuserv) from command line.
@rem Takes the two file to compare as parameters.
@setlocal
@set f1=%1
@set f2=%2
@set f1=%f1:\=/%
@set f2=%f2:\=/%
@set emacs_cd=%CD:\=/%
@set emacs_client="c:\emacs\p\070403\emacs\bin\emacsclient.exe"
@%emacs_client% -n
@%emacs_client% -e "(setq default-directory \"%emacs_cd%\")"
@%emacs_client% -n  -e "(ediff-files \"%f1%\" \"%f2%\")"
