How to trigger a Windows Firewall popup?

Question

Windows

In some applications, when you first access the network, the firewall itself shows a window with a suggestion to make an entry in the policy, and in other cases, such a window is not shown. What does it depend on and how to call it in your application?

Answer 1

EMNIP, a suggestion to add an entry to the firewall appears if the application opens a port for incoming packets (listen).

Answer 2

The window appears when there are no rules for the outgoing connection.
Perhaps the installer creates these rules, so the window does not appear
(Utorrent example, which itself creates this rule)
In order for the window to appear, you need to delete the rule for the port or application (outgoing) if they exist, if there is a built-in firewall
If there is a third-party antivirus, then perhaps it processes the rules itself and turns off the built-in firewall
