You should always run Windows Firewall even if you have another firewall turned on. Turning off Windows Firewall might make your device (and your network, if you have one) more vulnerable to unauthorized access.
To turn Windows Firewall on or off, select the Start button, open Windows Defender Security Center > Firewall & network protection, choose a network profile, and then under Windows Firewall, turn it on or off.
Note: If your device is connected to a network, network policy settings might prevent you from completing these steps. For more info, contact your administrator.
