Microsoft has release SQL Server 2005 SP2 as of yesterday February 19, 2007. The list of bug fixes contained in SP2 are detailed KB921896. The readme for the service pack is here, and the Service Pack download page is here.

Microsoft Virtual PC 2007 is a free download and is fully Vista compatible, as both a quest or host OS. I downloaded and installed it and it ran all my existing 2004 VM's with no problems, I did however update the Virtual Machine Extensions in all the existing VM's.

You can download Virtual PC 2007 here.

Happy downloading!
