WSUS SP1 (Windows Server Update Services) download link
Just spotted that WSUS SP1 is available for download. SP1 now supports updating machines running Windows Vista, comes with a newer version of MSDE and supports SQL Server 2005. Gives me my weekend upgrade task at home :)
Follow this link for the WSUS page on microsoft.com for more information and download. Happy patching.
Cheers,
John.
