Sorry about the delay. I havent had much time recently.
There is a very simple and free way to achive what you are wanting to
do.
Firstly check out
http://tinyurl.com/ednh7
Thats the traditional chinese keyboard layout.
Then print that out and all you have to do is use that as a refrance
once you have changed your keyboard settings.
Now you know what keys do what you need to change your keyboard
layout.
#
Select Start->Control Panel.
#
If you're viewing by categories (the default), click Date, Time,
Language, and Regional Options.
#
Click Regional and Language Options.
#
Click the Languages tab
#
Click the Details button
#
Click the Add button
#
From there select your language and keyboard settings, alough it should
do it automatically. Press Ok.
#
Now just change the default input language.
Note: you will have to change this evry time you want to but another
language in. E.g you would have to change it back when you wanted to
type in english, I belive.
