You shouldn't turn off Windows Firewall unless you have another firewall turned on. Turning off Windows Firewall might make your PC (and your network, if you have one) more vulnerable to unauthorized access. To turn Windows Firewall on or off:
- On Start , scroll down to Windows System > Control Panel > System and Security > Windows Firewall.
- Select Turn Windows Firewall on or off. You might be asked for an admin password or to confirm your choice.
- Under the appropriate network setting, select Turn on Windows Firewall.
- Note: If your PC is connected to a network, network policy settings might prevent you from completing these steps. For more info, contact your administrator.
