Upgrading to the current version?

So I went to a Microsoft launch event a couple weeks ago, a few of the giveaways were a Free license to Microsoft Office 2007 and a 180 trial of Microsoft Windows Vista Ultimate.

Now, I’m not in a position to just throw an OS around on just any machine, so I installed VMWare Server and installed Vista under a new Virtual Machine. All went well for awhile (I was underwhelmed with Vista, but that’s a post for another day) until I attempted to do a software update. The screenshot below tells me that my version of Vista (which came from Microsoft’s own DVD given away at the Office 2007/Exchange/Vista launch event) has expired as it’s only a beta.

That’s a damn shame. Microsoft had launched Vista to business partners last winter, and Vista was already available to retail by the time of the launch event, so why the beta DVD? I checked with the version number, the disc and anywhere else I could think to look and found no mention of a beta installation. Perhaps Microsoft doesn’t support their own software?
