Script for Regional Language Setting!

Hello...
I'm newbie in Script. I want some script that will change my system regional setting & language setting..
Is it possible to write any script that will change the same. If yes please help...

Thanks..

When I added Japanese support to my machine (I'm a anime fan), it presented me with a handy little task icon to swap back and forth between it and my normal English. Such a script honestly never occurred to me. Even if you wrote it, I'm pretty sure you'd have to disable uac for it to function.
