I had suggested
sfc /scannow to help assure all was still well after the failed upgrade.
Others have successfully upgraded to Windows 10 after uninstalling their a/v & 3rd party firewall.
If you do so, use the removal tool, if applicable -

I am unaware of the exact meaning of your error code. It's perplexing to say the least.
I do appreciate your suggestions and comments. Whenever I run into a problem like this I have a standard procedure that I use for troubleshooting.
1. I do a "clean boot" (run msconfig-hide all Microsoft services- disable what's left- reboot)
2. Open a command prompt with administrator privileges.
3. Using the command prompt I run procedures that I think will help isolate or clear up the problem ( "sfc, dims, etc" )
4. Where possible I include the following string at the end of the command line. >"%userprofile%\Desktop\name of procedure- date- time.txt".
5. This gives me the output of the cmd in a text file that I can examine and save for future reference.
6. I reboot between each procedure to eliminate pending flags.
Any suggestions for improving my approach to troubleshooting will be greatly appreciated. I'm a 79+ retired test engineer that still enjoys the challenge of learning new ways of doing business
New information: I spent over 5 hours with Microsoft troubleshooting this problem. I gave them access to my system and watched them repeat most of what I had already done. My case has now been elevated to the next level. Microsoft took some information with them to evaluate and will call me on Sunday at 1400 hours CST. I will pass on any information that comes from that
Again thanks for all of your efforts and please keep them coming. Who knows, the next one may be the solution.
