I think we have a solution for this since Emacs 26.1.  From NEWS.26:

  ** Intercepting hotkeys on Windows 7 and later now works better.
  The new keyboard hooking code properly grabs system hotkeys such as
  'Win-*' and 'Alt-TAB', in a way that Emacs can get at them before the
  system.  This makes the 'w32-register-hot-key' functionality work
  again on all versions of MS-Windows starting with Windows 7.  On
  Windows NT and later you can now register any hotkey combination.  (On
  Windows 9X, the previous limitations, spelled out in the Emacs manual,
  still apply.)
