Windows 8 was designed to work better in more locales all over the world. Working with developers like you, we can complete these globalized experiences by releasing apps that are relevant in more locations around the world. By translating using machine translation or localizing using a human translator, you can make your Windows Store app available in more languages and reach more markets and larger audiences. While making apps available on a global scale has always been a priority, with Windows 8 this process is easier than ever.
