I Just recently obtained Windows XP Professional edition legally (paid for), and little did I know I installed a Chinese version, and now I need help converting it from Chinese to English, because I am certainly not going to pay lots of money to buy an English version, so please don't reply telling me to buy another one. All I really need is a program of some sort that will convert my Chinese Edition to English without any problems or paying any money. Please don't refer me to microsoft.com because I tried there many times and it didn't help. (PS: The day I installed this it was in English, before installing this I selected English (United States) and yet it installed in chinese so I am in need of help please respond ASAP) Thanks.
