Decided not to extend the previous thread, getting too long
No Windows updates have been offered for the computer with Vista since the dates mentioned in my previous posts. Not even WD definitions updates. The computer with Windows 7 updates just finenow, although it had some update problems previously. It's getting close to three weeks now, and I have not one clue about what the problem might be.
It's like some connection has been lost or corrupted and my computer is not even attempting to search for updates. Or the update servers can't recognize this computer. Totally weird! So....as an experiment, I changed my settings to automatically download and install updates, instead of informing me first. We'll see what happens after a few days.
I believe there was a link in the other thread that lead to a diagnostic that would show what might be wrong, but the link didn't work for me. Any ideas as to what to do next, fellow forum members? All quick scans indicate that there are NO problems with malware
