Windows 7 includes support for a variety of languages. Even if you use the English interface, Windows 7 lets you type in other languages. Typing in a language such as Chinese requires a system to transcribe from Latin characters to Chinese symbols. The official system to do this is called Pinyin. Typing in this romanization system with the correct settings displays Chinese symbols on the screen. Possible symbols appear as you type to cut down on the time it takes and so you don't have to type the entire sound.
