I am cautiously saying that you fixed it. I have the following most recent entry in the Update History:
2018-12 Security Monthly Quality Rollup for Windows 7 for x64-based Systems (KB4471318)
Installation date: 12/19/2018 12:29 AM Installation status:
Successful Update type: Important
This is the first Monthly Security Rollup that I have been able to get to install since September.
Since the updates only install on shut down, I shut the machine down and powered it up again. On power up it restarted twice saying that it was configuring Windows Update both times. It also took about 10 minutes to completely reboot. I will definitely say it is fixed after it has been powered on for 1/2 hour or so and shut down again. Windows Update downloads the updates during that 1/2 hour and applies them on shut down. There should not be any Failures (I hope).
Do I have to worry about the previous September, October, and November monthly updates not being installed?
I am very optimistic that this is fixed. I will post this in a follow up posting tomorrow after some testing. I could never have attempted to fix this on my own. I want to say that following your very complete instructions made all the difference to me in resolving this issue that has plagued me for months.
Requested Fixlog.txt is attached here:
Dropbox - Fixlog.txt
I did not attach CBS.log since I am confident that this is now fixed.
If you are ever in NW Indiana or Chicago, contact me and I'll buy dinner anywhere you want to go.
Thank you, Thank you, Thank you.
