I have installed a russian copy of windows XP on my desktop, and I can't seem to change the language of the GUI to the English language... I got ALL of the programs to install and run in english, but I can't get windows to change the language that it is using... I have already tried to change it in the regional settings and I also tried installing the MUI... Nothing works... What should I do?

I can't install russian thru Regional Settings (coz of no WinCD or WinSource on HD). I need to make my PC to be compattible with russian language (not only text files).

Any idea how to do that?
