LIPs and Pre-installed Vista software

I recently bought a laptop running Vista in South America. Obviously
everything is in Spanish, but I have seen on a post in the forum that soon
Language Interface Packs will be available to change the language of the
menus, options, dialogues etc.

Does anyone know if these will also provide translations of the software
such as IE7, Windows media player, Windows Movie maker etc...?

If not, is it possible to get different language versions of these? I have
already tried downloading IE7, but it detects I am running Vista and says i
already have it installed.

Thanks for any help
