Well, while I still can't get the homegroup to work, I've managed to allow all my computers to access each other. Even though my PC has 10tb storage I also have a NAS.
One issue was on Kaspersky firewall - it though my wireless and ethernet connections were public. Changing them to private was one step.
Then came the credential manager. Deleting all the windows credentials and adding them back with the same passwords and user names sorted it. You have to be careful about user names. While my laptop had John as the name in user accounts, in user profile it showed as johnpc. I used that with the generic password hey presto, they all connect, PC, laptop and NAS.
So there is no need for homegroup. What a waste of time as none of the Windows 10 forums got anyway near sorting my issue.
