I used the Windows+X feature to start up control panel and make a recovery USB stick with everything. I used that and it's working fine now.
It looks like the owner had kept all their apps during the upgrade but they didn't want to pay to figure out what app it was. So we made the recovery stick, used it and it's all good.
So after a few hundred upgrades, I finally encountered this one. At least it's working now better than before on any prior Windows version.
I've been diligent about not accepting MS 'invitation' to upgrade to Windows 10 for almost a year. One day it just appeared. And my computer hasn't been the same. One laptop, it just can't figure out how to install the latest update.
My main desktop is pretty much kaput. Freezing, hanging...I've ended up screaming, "what is this !@#$ DOING?"
Now I can't open anything. I click on the Start button to reboot, it highlights and then nothing else. I try to open anything and the 'Operation has timed out'. I try some basic Windows settings and it now doesn't have a program associated with it.
I'm now wondering why does anyone put up with Microsoft anymore.
