Windows 10: Computer not showing up on network after Win10 2020 update.

So I just updated computer A to Win10 2004 19041.264 and now computer B ( Win10 1909 18363.836) can not see it. The ethernet network ( via cable ) was working perfectly before the update.

There must have been a change in the updated computer A somewhere but I cannot work out how to get them both talking again. Any ideas.

Best

Edit: when I do an Ethernet reset on Computer B it tells me 'Ethernet' doesn't have a valid IP configuration - not fixed.

Win10: windows update stuck at never ending loop ?

When in win10:

• Update&security -> Windows update -> Finding update... .... .... ....

Planning to download the latest Win10.ISO (vers.1803) and manually update:
- Then wait that my ordered new SSD arrives and clone the old HDD to it.

No computers show in Network

If we understood it correctly, the computers still do not show the Network tab after troubleshooting computer B. You may be correct that the firewall is blocking the network connection. You can try resetting the firewall settings and see if the issue will
still persist. Follow the steps below:

• On the Search bar, type CMD.
• Right-click the Command Prompt from the search result and select
  Run as administrator.
• Type this command: netshadvfirewall reset and press
  Enter.
• Once you are done, restart your PC.

We will wait for your update about the result.
