Windows firewall opens ping and disables the configuration method of ping

When I went through another local Ping computer on the same LAN (that is, on the same LAN segment), I found that if the firewall was enabled, ping would not work anyway. Once the firewall is turned off, ping is ready to go. Why is that? How do you set it?

The reason is that today's computer systems, for security reasons, do not allow external hosts to test ping by default. However, in a secure LAN environment, Ping testing is also necessary for administrators to conduct network testing. How do I change the Settings? The XP system is different from the WIN7 system:

Windows XP, Windows Server 2003:
Windows firewall -- > Advanced - > ICMP -- > Set - > Check "allow incoming echo request" > Sure - > And we're done.

Windows 7, Win 2008 R2, 2012 R2:
Windows firewall -- > Advanced Settings -- > Inbound rule -- > Find "file and printer sharing (echo request -ICMPv4-In)" -- in the list > Right-click to enable the rule and set it to 'allow connections' in its properties > Sure - > And we're done.
To disable ping, just check the box.
