I have a Lenovo Ideapad. It comes with Win7 home premium (english). I would like to upgrade it to ultimate. Is there a way to do it? , besides wipe out the entire HDD and re-install with Ultimate and going through loaders etc. Since the OEM branded home premium is already activated. The main reason I want to upgrade to ultimate is that they support multi-language display in Windows. If there is another way to support other languages, (chinese) then I won't need to upgrade. Thanks.
