If you misconfigured the Windows Firewall in Windows 10 and it started giving you network issues, it is a good idea to reset it. By resetting it, all the custom rules will be removed, and the defaults will be restored. There are two ways to reset Windows Firewall in Windows 10. In this article, we'll review them both.
Windows Firewall is a great feature in modern Windows versions. It was introduced in Windows XP and improved in Service Pack 2. But the firewall was still very simple. It was good at securing inbound connections and protecting against simple threats.
Finally, Windows Vista redesigned the Firewall to be based completely on the Windows Filtering Platform API and IPsec integrated. It added outbound connection blocking and also introduced an advanced Control Panel called Windows Firewall with Advanced Security, which gave fine-grained control over configuring the firewall and made it robust. Further releases of Windows made the firewall smarter with multiple active profiles, coexistence with third-party firewalls, rules based on port ranges and protocols and several other improvements.
To restore the default Firewall configuration, you can use Windows Firewall with Advanced Security, or the console utility, netsh.exe. They will both allow you to revert the changes made to Windows Firewall all at once. This is very useful if you have messed up your firewall configuration accidentally or some application did it.
