Hi Gary. I'm Greg, an installation specialist and 10 year Windows MVP here to help you.
They have broken networking in Windows 10, some believe deliberately to push us to use OneDrive for file sharing. I'll review this option later on.
I'll give you everything possible to try for files sharing problems so at least something will work. If you need help performing any steps I am standing by here to help:
See here for how to share files and printers over network after removal of HomeGroup:

If you want to express your opinion on this to Microsoft use the Feedback Hub app in Start Menu where developers are tasked to process consumer feedback. They will not even see it here. This is a tech forums staffed mostly by volunteers trying to help others with your problems.
If you want to post back a Share link from your Feedback here others who see this thread can vote it up and add to it.
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
