Windows Defender Free Firewall

As a user of Windows, you may have noticed that in many cases it is useless to give an instruction to the Windows Defender Firewall. For strange reasons, even if we indicate permission for a certain program, he asks us again. If you want to have real control over this add-on, use Windows Firewall Control.

The program will give you access to the basic functions of the firewall, but with sliders to control the degree of security or filtration. The simplest thing is to choose a security profile, from completely deactivating the leaks to being completely strict without letting anything happen.
