I am looking into pre-ordering Windows 7, but I have been trying to find out more info about this "multi-lingual user interface pack" before I make a version decision, but have been failing. Currently I use the windows IME to write in different languages, and I switch my region if a program needs me to. Is this just a region-changer without needing a restart? I am not sure what improvements this offers over the natual multi-language support that gets offered to all other versions of Windows...
