I must stress that Language Packs do not do many of the things people often think they do. Download and installation for Enterprise is usually done by system administrators, but Ultimate users can just run Windows Update, it's easy! Language Packs for the Windows system and Internet Explorer are free with the Windows 7 and Vista 'Ultimate' and (site license and IT department permitting) 'Enterprise' versions. In Vista you don't even need language packs to use the new handwriting feature, but beginning with Windows 7 the handwriting feature is bundled with language packs. Windows Language Packs are not necessary for reading or writing in Chinese, unless you want to add Chinese speech features, and add Chinese handwriting recognition input to your Tablet PC Input Panel (in addition to the traditional Chinese handwriting input already in a standard system). This means the user interface, or 'UI': menus, dialogs and other basic information.
Language Packs change your 'Display Language'.
