Thought I would update this thread because last night I was finally able to successfully install KB 2952664 and KB3035583 after many months of trying everything I could find written on line about these codes. Let me say up front that I am not advocating anyone else do it this way,but in desperation I used a pc repair tool from tweaking.com. I am normaly averse to any of these programs but I had read elsewhere that this program worked for another person who was having the same trouble as I was,so before doing a clean install I figured why not give it a shot.
It took a few hours to run through the entire repair sequence but as soon as it was finished I was able to install the two updates via Windows Updates. As soon as they installed successfully the Windows 10 icon appeared in the task bar,which of course would never happen unless the KB3035583 update was installed.I can't help but wonder if all of this was the result of the major infection problem I had many months ago?
Anyway,just wanted to thank Ztrucker for the advice and many suggestions as I tried to work thru this ordeal. It's been quite a ride to say the least.
