The Windows Firewall is a built-in security application that comes with Windows OS since the beginning. The software is built to filter network data transmission to and from your Windows system.
The Firewall will block any suspicious and harmful connection depending on the threat level.
The users can configure the Windows Firewall settings as per their need to block or open port in Windows 10 and other versions. However, at times the Firewall may block ports or programs accidentally by user’s or administrator’s misconfiguration.
