There is something that is called "Multilanguage User Interface". I don't know about the prices in other countries, but in germany a Windows XP pro MUI version only costs about 4 Euros more than a standard XP pro licence. I am using this kind of installation at work and it works perfectly fine. It works like this: Install Windows XP pro (english) Install any language pack you like (I can't find a list, but you may start looking here: Windows XP Home and Professional Editions) Set your regional settings to the standard language (this is a per user setting, although you may define a default language) Microsoft says that merely all languages that are available at these 4 cds will change 98% of all text boxes. I can confirm that for german, englisch, polish italian and spanish. A great thing to do, but be careful with service pack 2 as there is a lot of new text in it. I heard that MS will be releasing the MUI version a month later that SP2 which means that it will be appr. at the beginning of september! Nephilim P.S.: BTW, Office 2003 also features this MUI installation. Other programs and tools, may set their language within the registry for CURRENT_USER. So there you have you MUI installation!
