As Microsoft expands into more and more markets, scaling and tailoring products to meet global needs becomes a serious challenge. Microsoft Windows Vista currently supports more than 200 locales (100+ languages), and yet this covers only a fraction of speakers worldwide. As a company, we are moving towards a more extensible model for international support that will empower users to create and share customized solutions in the international space. The Microsoft Locale Builder provides a way to extend and modify the set of locales that Microsoft ships with your own regional and cultural data. The Microsoft Locale Builder was created to support customers in regions without built-in Windows locales as well as customers seeking to modify locales that they are already using. Customers will be able to add support on their own timeline without having to wait for new releases of Windows. Microsoft Locale Builder will also allow corporations, governments, universities, and special-interest groups to generate and easily share custom locales on Microsoft Windows Vista.
