Where are Windows Firewall Rules Stored?

If you are running Windows operating system on your computer, then you must have heard of the Windows Firewall.

It is a built-in security feature that helps protect your computer from unauthorized access to your network and system.

The Windows Firewall works by blocking incoming and outgoing traffic based on a set of predefined rules.

But, have you ever wondered where these rules are stored? In this article, we will explore the location of Windows Firewall rules and how you can access them.

Windows Firewall Rules

Before we delve into where the Windows Firewall rules are stored, it is essential to have a basic understanding of how the Windows Firewall works.

Windows Firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.

These rules are configured by system administrators and users and define what traffic should be allowed or blocked based on different criteria such as port number, protocol, IP address, etc.

Where are Windows Firewall Rules Stored?

Windows Firewall rules are stored in the Windows Registry. The Registry is a hierarchical database that stores configuration settings and options on Microsoft Windows operating systems.

All the Windows Firewall rules are stored in the Registry subkeys located at

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy.

Under the FirewallPolicy key, there are several subkeys that correspond to the different network profiles (domain, private, and public) and the types of rules (inbound and outbound) that have been configured.

Each subkey contains a set of values that define the properties of the rules, such as the name of the rule, the program or service that the rule applies to, the ports that the rule is applicable to, and so on.

Yes, you can delete Windows Firewall rules. You can do this by accessing the Windows Firewall settings and removing the rule that you want to delete.

Alternatively, you can use the Command Prompt to delete a specific rule by using the "netsh advfirewall firewall delete rule" command followed by the name or number of the rule you want to delete.

It is important to note that deleting a rule may affect your computer's security settings, so you should only delete a rule if you are sure that it is no longer required.

How do I copy Windows Firewall rules?

If you need to copy Windows Firewall rules from one computer to another, you can use the "Windows Firewall with Advanced Security" snap-in in the Microsoft Management Console (MMC).

Here are the steps to copy Windows Firewall rules:

Open the "Windows Firewall with Advanced Security" snap-in by typing "wf.msc" in the Windows search bar and selecting "Windows Firewall with Advanced Security" from the results.

In the snap-in, select "Inbound Rules" or "Outbound Rules" from the left-hand pane, depending on which type of rule you want to copy.

Right-click on the rule that you want to copy and select "Export". Choose a location and name for the exported rule file and click "Save".

Transfer the exported rule file to the destination computer using a USB drive or other means.

On the destination computer, open the "Windows Firewall with Advanced Security" snap-in and select "Inbound Rules" or "Outbound Rules" from the left-hand pane, depending on which type of rule you want to copy.

Right-click on the right-hand pane and select "Import". Browse to the location where you saved the exported rule file, select it, and click "Open".

The rule will be imported and added to the Windows Firewall rules on the destination computer.

Note that the exported rule file contains the configuration settings for the rule, but not the actual program or service associated with the rule. You may need to manually adjust the rule settings if the program or service name is different on the destination computer.
