In this post, we will see how you can turn on or turn off the Windows Firewall in Windows 10/8/7. Before you do this, it is important to know that you should not turn off or disable Windows Firewall unless you have another third-party firewall installed and enabled as it makes your computer and network more vulnerable to malware attacks. If you have one enabled, it will automatically disable itself. Nevertheless, if you have the need to disable it manually, then this post will show you how to do it.
