Why can't I set ctrl esc tab?

[Sally]

I do this:

(global-set-key [C-tab] 'buffer-stack-down)
(global-set-key [C-M-tab] 'buffer-stack-up)


In my buffer I do the key stroke
C-h k C-tab
and I get the correct binding
C-h k Esc C-tab
and I get that the key is not bound


Why doesn't it work?

Guess it has something to do with running the windows version?

; this set the esc ctrl tab
(global-set-key (kbd "<ESC> C-<tab>") 'buffer-stack-up)
; this set the alt ctrl tab
(global-set-key [C-M-tab] 'buffer-stack-up)
