Some versions of Vista, I believe the Home and Home Premium, won't let you change the language settings once it's installed.



If you have Ultimate you can use some programs released from Microsoft - Or search the Microsoft Vista support pages for help (good luck).



You'll probably have to back up everything, which you should do anyways, and reinstall your OS to change languages.



You can use your Backup disk or if it's presintalled you can usually hold down F11 on Boot-up to start reinstallation.
