System Language Change


New Member
Hi guys, sorry if this post is redundant. I changed the display language of my Windows 7 Ultimate to English from Mandarin, but many parts of the computer experience are still in Mandarin. For instance, when I go to twitter, facebook, etc. I'm taken to the Chinese portal. Also, installation for new software is still in Chinese. How can I change everything to being in English? Is it because this Windows OS is a Chinese copy and this is not fixable?
