I tried your fix, but had no change in the results. I have a desktop with Intel processor and Windows 7 Professional. Then I went into the settings for Windows Update, and changed the option to letting me select the downloads BEFORE downloading them. The first time I shut down (I assume because that was the operating "session" during which I changed the download option) I had the same old problem, but then I shut down again, and it did NOT try to download any updates, and it booted just fine without any error messages. Then I went BACK into Windows Update and changed the option back to "automatically update". This produced a window in which I was given an "Update Now" button. I clicked on that, they downloaded without a hitch, I was instructed to restart the system, which I did, and the system booted the next time without any difficulty. Now everything seems to be working perfectly. Thus, this was a very simple fix and I doubt that it took over five minutes.
