If you plan to install a third party firewall then you should first turn off the Windows Firewall. If your Windows computer is not used to connect to the internet, then you should turn off the Windows Firewall as it would be using the system resources for no reason. You can turn off the Windows 7 Firewall using the steps below :
- Open Control Panel. Click on System and Security, then click on Windows Firewall
- This would open the Windows Firewall window. Click on Turn Windows Firewall on or off on the left side menu
- In the next window, choose the option Turn off Windows Firewall for Home or work (private) networks or Public networks or both.
- Click OK to save the settings.
