Run M.S. Word and Open the "normal.dot" Template file located at ...

C:\Documents and Settings\{YourLogonName}\Application Data\Microsoft\Templates\Normal.dot

... where "YourLogonName" is the name you use to logon to Windows XP - sorry for being pedantic. In Word, go to Tools menu, Language, Set Language, and select your preferred (default) language, click Ok then Save (Ctrl + S) and Close (Ctrl + W) the template document. Start a new document (Ctrl + N) which should now be your preferred language by default. Regards
