Minimal working .emacs example

(defconst backups-dir "~/.emacs.d/backups/")

;; auto-save
(setq auto-save-default t
      auto-save-interval 0
      auto-save-timeout 5
      delete-auto-save-files t
      auto-save-list-file-name (concat backups-dir (format ".auto-save-%s"
(emacs-pid)))
      auto-save-file-name-transforms `((".*" ,backups-dir t)))


I run Emacs 24.3 on Windows 7 x64 with "runemacs.exe"
