There are many input methods. As for Windows, the default method is not so good as sogou or google. Pinyin method is most widely used.

mmm, i think u must learn how to type it.there're two different ways to type . one of them called"汉语拼音"it means type it by how to say it the other called"五笔"it means type it by how to write it most of we chinese use 汉语拼音,and u can learn it :)

If you are serious about learning Chinese, I might suggest the NJStar package. You get a very powerful word processor, pinyin annotator, dictionary bot, IM software and text to voice software.

You need to mention the O/S. There are different methods for different O/S.
