I think I have made progress. My computer seems to be much faster now. After running tools at this site to clean up the computer, things were found and that helped.
Next I did as administrator a sfc \sannow and that found corruption that it could not fix.
Then I did a DISM scan and found out that I needed an ISO file to repair. So, I downloaded a matching file for it from Microsoft. Then, I learned that I must mount that ISO file to a virtual drive for DISM to access. Cyberlink sort of did that for me easy enough after I right clicked the ISO and chose Mount to a virtual drive. I did that and ran
DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:L:\Sources\Install.wim:1 /LimitAccess
After running it with with the ISO that had been saved to desktop and mounted to a virtual drive L, the scan came back clean. There were no more files corrupt or not repaired. After that I did another sfc /scannow, this time it repaired more files and pronounced me clean. I then opened the virtual drive L with Cyberlink and it unmounted it. I deleted it then.
Then, I downloaded the Norton Remove and Re-install tool for my Norton 360 Premier. I did that because after all this work, it seemed somewhat buggy. It is good to do this with Norton at times.
I can now move about easily for a change, at least until Windows does another corrupt update. BTW yesterday's update made it worse. I hope this helps. I thought this was going to be above my paygrade, but it worked. I was to the point of thinking of starting from scratch. At least for now I don't have to do that. There are several places that you can get a step by step which is what I did. Here and Windows10forum were a big help. I hope this make sense since I am by no means an expert or techno person.
