Windows Update not pushing Vista SP2
On two computer systems, I have fully legal and validated Vista 64-bit installs. On both machines, I use the Windows Update system to ensure I have all the latest patches and updates. Both machines pass Microsoft's "Genuine Advantage" checks. In both cases, the machines are running service pack 1. According to Wikipedia, Microsoft released Service Pack 2 for Vista on April 28, 2009, and it was released to Windows Update on May 26, 2009. Neither computer system is "seeing" SP2 as an available upgrade. Why not?
