Microsoft has released an update that makes software for its Zune device available on Windows Vista. The software can be downloaded at the Zune website.

According to Microsoft's Zune Insider blog, the update also improves Zune's software installation process.

Microsoft released its Zune video and music player and accompanying Zune Marketplace online store in the US in November, but it was initially incompatible with Vista. However, at the time the company said it would be available in plenty of time for Vista's consumer release, which is scheduled for January 30.

Some users already have adopted Vista for personal use by installing the late test releases of the OS on their machines. Microsoft also released Vista to businesses on November 30, but companies are not expected to adopt the OS widely until next year or even 2008.
