I think Emacs ought to follow the standard behaviour on ms-windows.
Submit a bug report :-)

OK, here's an improved version:

(require 'assoc)
(defvar my-frame-position-x-offset 20)
(defvar my-frame-position-y-offset 20)
(defvar my-frame-position-taskbar-height 30)

(defun my-frame-position ()
  (let ((left (+ my-frame-position-x-offset 
		 (or (frame-parameter nil 'left) 0)))
	(top (+ my-frame-position-y-offset 
		(or (frame-parameter nil 'top) 0))))
    (when (or (> (+ (frame-pixel-width) left) 
		 (display-pixel-width))
	      (> (+ (frame-pixel-height) top 
		    my-frame-position-taskbar-height)
		 (display-pixel-height)))
      (setq left 0 top 0))
    (aput 'default-frame-alist 'left left)
    (aput 'default-frame-alist 'top top)))

(aput 'default-frame-alist 'user-position t)
(add-hook 'before-make-frame-hook 'my-frame-position)
