Microsoft release the final update for Vista that addresses a problem when trying to eject an iPod.
The release is for users worldwide and works with the latest version of Apple iTunes to correct an issue that caused some iPods to become corrupted when ejecting them using Windows Explorer or the "Safely Remove Hardware" function in the System Tray.
I don't use my iPod on Vista, but some people lost their music when ejecting their iPod. Then you had to restore you ipod to get it to work again. The update will be available on May 22nd through automatic updates. You can get the update now by going to the direct download on Microsoft's website.
