Having read your thread in the Bleepingcomputer.com forum and other Google links on this error and if you have also tried those, should it be an Internet problem, open a Command Prompt (Admin) and enter these cmds then check after the the reboot.
netsh winsock reset
shutdown /r /t 00
Thanks for the idea about a different direction, unfortunately it didn't help.
As you can see from what was suggested over there (I actually had tried most of the suggestions previously) I've tried about everything imaginable and nothing seems to help. I really don't want to blow everything away and start over with a new configuration, I have AutoCAD in several auxiliary programs used for design work that are very intricate to reinstall on a system. On top of that I'm disabled and have to use Dragon NaturallySpeaking software to control my computer. It works great I can do everything using it that I could previously however, when you're doing a complete scratch installation on your computer it takes a while before you get to a point where you can use it (or even Windows recognition for that matter).
I'll keep plugging away, I know sooner or later I'll run into something that solves the problem. Meanwhile, fortunately the only thing it affects is a Microsoft store and apps from it and forcefully none of those are things I use on a regular basis.
