Ok, I checked for Windows Updates and only 2 were found. One of them was an old one (one of the 5 that had failed previously) and one was a new one. What happened to the other 4 updates that had failed previously?
I tried to install them and while they were downloading, I was browsing the net (e.g. reading your responses to this thread). The last time I had checked on them, the downloading was at 90%. After several minutes, while I continued to surf the net, my system froze. I wasn't able to check/verify whether the download and installation of the updates had completed or not. I had to force shut off my computer and restart, since it was locked up and I couldn't do anything. I booted it up again and checked for Windows Updates one more time. The same ones appeared. I tried to install them once again and this time they downloaded and installed completely. After they finished installing, I had to reboot and the system configured the updates before restarting.
I am still in Clean Boot Mode. Also, I never manually restarted the Windows Update Service, but I'm assuming it automatically did so when I restarted after restoring the repaired SOFTWARE hive using RegBack?
Checking for updates now (again) yielded 3 different updates for the same thing: Update for Microsoft .NET Framework 4.6.1 on Windows 7 and Windows Server 2008 R2 for x64
I'm about to try to install them next...
