Windows 10: Network problem between W10 and W7/8 PCs

I have, what seems to be, a common problem with my home network of one Windows 10 PC and several Windows 7 & 8 PCs. I can access the files of the W7 & 8 computers from the W10 one, but the W10 files cannot be accessed by the others, although all PCs show up on the network on each one. The W7 & W8 computers talk to each other with no problem. A printer connected to the W10 PC can be accessed by the others with no problem.



The W10 PC is version 1803, i.e. without the Homegroup function. All PCs have all their latest updates.



I have checked all the settings suggested in other peoples’ advice, such as:

files/folders set to share with ‘Everyone’ and with Full Control;

password protected sharing is off;

network discovery is on;

Function Discovery, SSDP, UPnP Device services are set to automatic & running



I have Norton installed on all of them with ‘Full Trust’ given to all on the network. I tried temporarily turning off the Norton Firewall (Windows Discovery already turned off), but that didn’t solve it.



I have gone over all the settings several times on each device, and restarted them several times, but I am now at a loss what to try next. TIA.

Network driver 'lost' on upgrade from W7 to W10

Just unpacked a new PC (HP Workstation) with W7. Installed OK and everything worked, without issue. Got W7 updates, loaded Office 2016 etc. etc... Then I ticked the box for 'upgrade to W10.

A little over two hours later I had W10. Except....

It seems to have lost the drivers for the Network device. And the only solution it could come up with is to (guess what) connect to the Internet.

It's a tower (so no WiFi).

Anyone got any suggestions?

 

Home Networks or Workgroups connecting W7 W10 systems

More test results:

W7: After creating a Home net group on W10 machine, the W7 machine stated, that there were no Home net group in the system and prompts me to create one. I expected in contrary an order to join one.

W10: After creating from new a Home net group on W7, W10 prompts me to join this one, but ending finally also in a "not found on system"

I removed both Home networks.

W7 explorer shows me the W10 machine, but could´nt access it.

W10 explore showed me the W7 machine, accessable and adding a legitimation for "everybody" on W7 allowed me to open a dataset in the W10 explorer.

Summary:

It was not possible by no means to connect a W10/W7 and a W7/W10 by a Home net group.

By the basic workgroup the W7 explorer showed me the W10 machine, but did´nt allow to acess it, the W10 explorer worked without problems with the W7 machines objects.

 

Home Networks or Workgroups connecting W7 W10 systems

I want to discuss possibilities to run home networks between mixed W10 and W7 nodes. My first information was, it is not possible. My own experiments lead to W7 not even recognizes the W10 node connected by the same Workgroup, there was a short time, W7
recognized but then W10 node again disappeared in the W7´s explorer.

If it is not possible to connect mixed W7 and W10 by an home network, how at least is possible a simple workgroup setup in both systems the same name, even tricky. It seems to me a problem to recognize user accounts crosswise to give access to certain datasets
on the other machine. Thank you for contributions, I hope I did not overlook a solution already given.

Another Test: Workgroup name the same, Username the same both logged in, password the same, the W10 machine appears at w7´s explorer, but no access allowed from W7´s explorer.
