Let's not forget that the server companion to Windows 7, Windows Server 2008 R2, is also available in RC form today. I'll have a lengthy write-up about this release out late today or tomorrow, but here's the word from the Windows Server blog:

As many of you know, Windows Server 2008 R2 Release Candidate (RC) is made available today to MSDN and TechNet subscribers, with broader availability from Microsoft.com on May 5th. As our final broad test milestone before RTM, this really is the best chance for you to download Windows Server 2008 R2 and put it through its paces while we continue our march to RTM.

With Windows Server 2008 and even more so with Windows Server 2008 R2, we want to promote the notion that IT instead should be considered a strategic asset to a business: enabling new scenarios, automating essential tasks, and dynamically provisioning and de-provisioning resources as needed to support the growing demands of an organization.

We’re confident that you’ll like what we’ve done with Windows Server 2008 R2. Download it and try it out when you get a chance, and don’t forget to let us know how you get on.
