a tool for change your OS language(not for English users)

   Hi, perhaps I'm being dense but before I run this tool I'd just like to know exactly what it does.
   For example, if I run it on an OEM Windows XP Pro Chinese installation does everything then display in English?  Totally, completely everything?  Can it be changed back?  Are you in Beijing?  Would you like to have dinner, lunch or coffee?  Ha-ha.
   Thanks - Joe
