Thanks (duh). It too needs to be documented.

We document all of the following in the Emacs manual:

 `w32-alt-is-meta' 
 `w32-pass-alt-to-system'
 `w32-capslock-is-shiftlock'
 `w32-enable-caps-lock'
 `w32-enable-num-lock'
 `w32-apps-modifier'
 `w32-lwindow-modifier'
 `w32-rwindow-modifier'
 `w32-scroll-lock-modifier'
 `w32-pass-lwindow-to-system'
 `w32-pass-rwindow-to-system'
 `w32-recognize-altgr'
 `w32-phantom-key-code'
 `w32-get-true-file-attributes'
 `w32-mouse-button-tolerance'
 `w32-pass-extra-mouse-buttons-to-system'
 `w32-swap-mouse-buttons'
 `w32-quote-process-args'
 `w32-shell-execute'
 `w32-charset-info-alist'
 `w32-use-visible-system-caret'
 `w32-grab-focus-on-raise'
 `w32-list-proportional-fonts' 

We should also document `w32-(un)register-hot-key'.
This seems to be a gross oversight.
