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.

I found this post and it works for me on Vista.

• open "regedit.exe" in run dialog
• Browse the registry editor to the location: HKEY_CURRENT_USER\Control Panel\Input Method\Hot Keys\
