I bought new computer in Japan which is Japanese version and I suffered much pain from this. I tried to search for the solutions. I found many and many solutions. I tried them. Some are not work. Some are too difficult. At last, I found the program “Vistalizator“. This one is brillant!! Please look at its website. It’s freeware and has a nice interface. We can just download MUI file (Language file for windows) and then use this program to load MUI file to your computer. That’s finished! Very easy, isn’t it?
