How to prevent Windows XP from stealing my input Ctrl-Space which is meant for Emacs?

Question

I am learning and using Emacs. What I found annoying is that Ctrl-Space input will be stolen by Windows XP to switch the language bar instead of setting the mark in Emacs.

Answer 1

The following works for me:

There is a windows freeware AutoHotkey which let you, for example, bind F12 to Alt-a.

Install AutoHotkey and bind C-Space to C-@.

Binding C-Space to C-Space doesn't work.
