Windows Vista Ultimate Language Packs

With the Windows Vista language packs, you can take advantage of the Multilingual User Interface (MUI) feature of Windows Vista Ultimate. This means that you can change languages as easily as logging off and logging on, and each user of your computer can use his or her preferred language to interact with the PC. So if your family shares a single PC, every family member can pick the language that makes him or her most comfortable. This is a great solution if you have a multilingual household or if one of you is learning a new language.
You can install as many languages as you want, but there are some important things to know first, about installing them. Because language packs contain language-specific resources for all the Windows Vista components, the language packs are large and take some time to install. The average download size is approximately 200 megabytes (MB) and may require up to 1,100 MB of free disk space to install. The installation process takes approximately 30 minutes. However, the time varies depending on the performance of the computer.
And one last fine-print note: 16 languages became available on January 30. The remaining languages will follow. We’ll post an update on this site when additional languages are available for download.
Language packs released to date: Chinese (Traditional); Chinese (Simplified); Danish; Dutch; English; Finnish; French; German; Italian; Japanese; Korean; Norwegian; Portuguese (Brazil); Russian; Spanish; Swedish.
