Can't access computers from outside internal network

My Windows 10 recently did the latest and greatest upgrade from microsoft.  Since the upgrade, I can no longer access computer on my internal home network from outside the network.  It has worked well in the past.  I can access them if they are all on the same network.  Is there a switch or option I need to allow to get this working again?

    I would check both the windows firewall (disable it for diagnostic purposes and see if it works then) and then your network firewall provided by your ISP (Set it to a lower security level). See if either of those make a differance. Then report back please.

  • What does this mean "under the apps"?  Can someone please explain how to do this?  I.e. "enable access from public locations".  Thanks in advance.

    In Windows 10 go to Windows Security > Firewall & network protection and turn off the Public network protection. 

    Works for me
