Another Update
Titan I am strongly leaning toward agreement with your assessment so far.
Checked for third party conflicts nothing appeared unusual, it does not seem to be very likely. Both my PC's have only three apps installed on both. They are: Google Chrome 76.0.3809.100 , Quicken R20.15 and Adobe Reader 9. Timing of the issues doesn't coincide to any changes that might have been made.
Checked the Windows Update History, and found that the last update occurred in the first week of July. About mid July a news report stated that Microsoft had found a significant problem, and they were issuing a critical update. I recall at startup one morning it was being installed, but it does not appear now the update history.
I then remember that Windows Defender had stopped getting virus updates at or near the date the other updates seemed to have stopped. I also recalled that when W10 came out, it appeared that Microsoft seemed to have merged Defender and the Firewall together. It seemed like you could not enable either of them without the other. I had suspected that in XP the updates was going around the firewall. Could it be, W10 this is no longer true and can Defender control the firewall and block auto updates. A check showed that the firewall was still set at its default value of medium.
Thus I ran a manual W10 update as a test. At the start of this update W10 seemed to show t that three updates were needed. The first showed that it was a Defender update. The two remaining were labeled as NET frameworks updates. When downloading was finished it appeared that only the last two were actually downloaded. After installation and restarting, it only occurred twice seemingly confirming that.
Without anything pointing to a cause, it appears that I have only two reaming options.
- Find a way to force the entire W10 operating system back to its defaults. I fear that this might end up causing more and new problems.
- Reinstall the entire operating system and hope that fixes it. 🙁
