Windows 11 Update Failed, then Windows Update failed

I was just offered the opportunity to upgrade to Windows 11 in the Release Preview Channel. I gladly accepted the offer. The upgrade downloaded, then installed (seemingly 100%), and then rebooted. Wi...

It seems that on many computers there is this problem!

Sounds like everyone's stumped. A relatively new, high end machine, running well (with this one exception), with updated drivers and bios, cannot receive an update that is offered by Windows update.... Something's wrong here. Isn't there some way to determine what is causing this?

Haven't given up yet. Tried doing a Diagnostic Startup (using msconfig) and elimination of all but MS programs from startup (using task manager) - just to see if there might be some installed program that was interfering with the installation. Remember, I've run sfc /scannow several times now and all's well there. When done disabling startup programs, I rebooted and then went to Windows Update and again tried to upgrade to Windows 11. As it rebooted I watched "installing updates" immediately jump from 0% to 77%, then it restarted. On the way back up, it again reported installing updates. I got to the deesktop and - yes, unfortunately, nothing changed. No error message. Windows update still asks if I want to upgrade to Windows 11. Again, a total waste of time. I'll attach a couple screen-shots here.

As I said, I haven't given up yet. I used Rufus (as recommended at https://docs.microsoft.com/en-us/windows-insider/ISOs) to set up a bootable USB drive using the Windows 10 ISO file provided at the Windows Insider site for the Release Preview Channel. I ran the setup from that USB drive and re-installed the latest version of Windows 10. After completion, my OS Build went from 19043.1263 to 19044.1263. I ran Windows Update and was surprised to see yet another Update was available. I installed it, and now I have a completely up-to-date Windows 10 machine that is enrolled in the Release Preview Channel and which is not being offered the upgrade to Windows 11 (at least not yet). Something tells me that this is precisely where I should have been all along. We'll see.

  Since probably ISO will be necessary - I found this:
