I have gone through the clean boot. And through the process of finding the offending process. I turned all 30 of my processes off, then turned on the first 15, followed by turning on only the second 15. The slow-system condition continued with all three of the restarts.
I seriously question if there is a conflict or a damaged process file. I also ran the sfc /SCANNOW, and the Dism.exe /Online /Cleanup-Image /RestoreHealth (both in the admin command window.)
I did find a slight improvement by turning off Animations in the Taskbar for the Advanced System Properties.
Did the Speccy scan I linked in my Oct 13 post reveal any likely suspects?
I also tried Defraggler, but that didn't provide any noticeable improvement.
I am currently using McAfee for my antivirus. Could that be a possible culprit?
Would Windows Defender would be preferable?. Does it provide comparable protection with less computer overhead (obstruction) than McAfee. Obviously, I am thinking out loud and digressing from my original post.
If you have any suggestions that do not allude to "rocket science" they would be greatly appreciated.
