Snipped from diff.el:

  ;; This package helps you explore differences between files, using the
  ;; UNIX command diff(1).  The commands are `diff' and `diff-backup'.
  ;; You can specify options with `diff-switches'.

So, altough diff.el is standard emacs, it is based on the external
program diff, which is standard on Unix varieties, but obviously not
on Win XP.
