By default, a new Windows 10 installation will have the firewall enabled and set to not respond to ICMP pings, even from hosts on a private network. This can resolved enabling the correct whitelist entries in the firewall.
Click the Windows menu icon, then start typing firewall to start listing programs. Select Windows Firewall with Advanced Security.
Select Inbound Rules (as we want the computer to respond to incoming pings).
Find the rules File and Printer Sharing (Echo Request). There will be rules for IPv4 and IPv6, and possibly for different network Profiles. Right-click the rule/s you wish to activate and select Enable Rule. Most internal and home networks currently run IPv4.
As soon as the rule is enabled the computer should start responding to pings.
