Delete a rule by program or service: These commands allow you to delete firewall rules that target a specific program (by specifying the program file path) or service (by specifying the service name). This is useful for removing rules associated with specific applications or services.

netsh advfirewall mainmode delete rule program="C:\Program Files\MyApp\MyApp.exe"

netsh advfirewall mainmode delete rule servicename="MyService"

Delete a rule by port: This command deletes a firewall rule based on a specific TCP port (port 8080 in this case). Clearing rules based on ports is important to control network communications.

netsh advfirewall mainmode delete rule protocol=TCP localport=8080
