i want to type chinese in my english window!

在 start > settings > control panel > regional and language options, 在lagnuages的頁面下方的supplemental language support 選取install files for complex.... & install files for east asian languages 這兩項, 然後在上方的text services and input languages 按details... 的button, 在settings 的頁面，install services 裡按add, input language 選 chinese (taiwan), keyboard layout/ime 選 chinese (traditional) - changjie (倉頡) 及chinese (traditional) - quick (速成), 按ok兩下，再在regional and language options 裏的advanced 頁面的language for non-unicode programs 內選chinese (hong kong s.a.r.), 再按ok就攪掂啦！

If you know Pinyin or speak mandarin fluently, Chinese input is already built in Microsoft Word. You only need to activate it by making a few configuration changes. Here's a link to show how this can be done. It works perfectly also in XP.

The above link works very well with simplified characters.
If you use traditional characters, follow this link:

You will have a choice of the two sets that coexist perfectly.
