Update:  Zune Software is now available in the directly from Microsoft in the UK here http://www.zune.net/en-GB/

We get a lot of questions about how to download the Zune Software in the UK, so we thought we would make it easy and post the link here:   http://go.microsoft.com/?linkid=9753463

You can download the Zune Software even before you actually get your Zune. This will allow you to make sure it runs on your computer and get a feel for the software.

Update: This link also works for Zune Software in Europe and the rest of the World as well as UK.
