Windows update stopped updating at, Windows Update Agent 7.6.7600.256, and no more updates in 4 days. I'm using Vista, and was installing a 500g HD, from the orginal 80g, so I was going for a complete install from format and I got about half of the necessary updates from Microsoft, and then the updates just stopped coming. I replaced the HD now to prepare for windows 7 or 8 or higher next year. I know there are 150 or so updates to go but the updates stopping midstream. Any ideas?
