On Tuesday the 19th of December, our Zune team issued a 22 MB update to make Zune compatible with Windows Vista. The update also improves the Zune software installation process, addressing some of the known issues  that users reported. It is the stuff customers will notice and appreciate. If you have not already downloaded and installed the latest bits, you should, even if you’re not running Windows Vista (yet).

You can install it via Microsoft auto-update, or go to Zune.net to get it.
