If your Windows XP is not in the language you would otherwise prefer, you should change it. And given that your computer out of the box is already capable of switching between all the world's major languages, and numerous dialects within a single language, you will not need to download anything, or even contact technical support. Changing the language on your Windows XP should be easy and take you no more than a few minutes.
