The Microsoft Language Portal offers terminology and UI translations from scores of international Microsoft products that have released. Microsoft Terminology Collection, Style Guides and UI Translations are all available for download from this site.
Microsoft Terminology Collection can be used to develop localized versions of applications that integrate with Microsoft products. It can also be used to integrate Microsoft terminology into other terminology collections or serve as a base IT glossary for language development in the nearly 100 languages available. Terminology is provided in .tbx format, an industry standard for terminology exchange.
Microsoft Style Guides are collections of rules that define language and style conventions for specific languages. These rules usually include general localization guidelines, information on language style and usage in technical publications, and information on market-specific data formats.
UI Translations are translations of the user interface text (UI strings) for Microsoft products and services. They are available for subscribers to the Microsoft Developer Network (MSDN) or to Microsoft TechNet.
