I had one hell of a time finding this page, all of the help pages, KB pages, etc. pointed to an outdated link on Microsoft's page. But if you are having the same problem here is a direct link to the download. This fixes all known issues with Visual Studio 2005 and Windows Vista, also this is not the Beta service pack that was released prior. This is the full blown released Service Pack 1 Update for Windows Vista.
