I just noticed that emacs/lisp/term/w32-win.el contains the following lines:

  ;; Keyboard layout/language change events
  ;; For now ignore language-change events; in the future
  ;; we should switch the Emacs Input Method to match the
  ;; new layout/language selected by the user.
  (global-set-key [language-change] 'ignore)

It is interesting that Windows generates `language-change' key event.
I guess it is currently ignored because it is not trivial to process it
in Emacs.
