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 comments under the blog Sorting it all Out (mentioned in sundar's answer) mentions this solution:

• Open RegEdit and naviagate to HKEY_CURRENT_USER\Control Panel\Input Method\Hot Keys
• Find the '00000070' (Chinese Traditional) or '00000010' (Chinese Simplified) key that has the values: Key Modifiers='02,c0' (Control) Virtual Key='20' (Space)
• Replace these values with, e.g. Key Modifiers='FF,c0,00,00' and Virtual Key='FF'.
• Log out/log back in (important).

This worked for me in Windows 7.
