Windows 10: Sudden Network Problems

Three computers (one Windows 7, two Windows 10) are on a home network; both Windows 10 computers are on 1803. Until today, all could share one printer connected to the Windows 7 computer and could share files from/to a public folder on one of the other computers. This is file and printer sharing, no passwords are used.

Today, I installed the latest Cumulative Update (KB4480966) on for one of the Windows 10 computers. I am not claiming that the update is the cause of the problems. Now, the networking is all screwed up.

1) Both Windows 10 computers can see the Windows 7 computer, but can not connect (share a file) to it. Both get an error message box, "Windows cannot access \\COMPUTER; there might be a problem with your network".
The "Diagnose" does not find the problem.
2) When I try to connect the Windows 7 computer to one of the Windows 10 computers, an error message saying "Enter Network Password" appears. But never before have I been asked for such a password. The Windows 7 computer will connect to the other Windows 10 computer.

Where do I begin to find a solution? Frankly, I have NEVER understood networking, even just a home network. Help!

Hi,

Thank you for posting in Microsoft Community.

First Verify if the WLAN service is started and set to automatic, if the WLAN service is stopped, I would suggest you to start the service and put it to automatic.

Step 1: Please follow the steps to
start the WLAN service.

• 
  Click on Start, type in services.msc
  and press Enter.

  Select WLAN Autoconfig from the list, Right click

• 
  Change the startup type to Automatic.
  
• 
  Click on Start button.
  
• 
  Click on Apply, Ok.
  

Restart the computer and verify if it works.

Also check if all the dependencies are also running. Try the steps to check Dependencies.

• 
  Right-click on WLAN Autoconfig and select Properties.
  
• 
  Click on Dependencies, you will find all the dependency services under box labeled this service depends on the following system components.
  

Step 2: Run an inbuilt Network troubleshooter.
