Ordinary users recommend that you always enable Windows firewall. 1. Turn on the firewall for home or public network environments to prevent unauthorized access; 2. It can be turned off when third-party security software has been replaced; 3. It can be turned off temporarily when professional debugging or troubleshooting problems. The operation path is Control Panel → Windows Defender Firewall → Enable or turn off the firewall settings and configure policies for different network types.

Windows Firewall is a security protection tool that comes with the system, which can effectively prevent unauthorized network access. Whether to enable or disable it depends on your actual usage scenario.

When should Windows Firewall be enabled?

If you are an ordinary user and only surf the Internet, office, and videos on a daily basis, it is recommended to keep the firewall turned on at all times . Its default settings are enough to deal with most situations to prevent malware from spreading across the network.

• When a home computer is connected to home broadband or Wi-Fi, turning on the firewall can help prevent potential attacks in the LAN.
• In public network environments (such as coffee shops, airports), firewalls can provide an additional layer of protection.
• If you are not sure whether a program is safe, the firewall can also pop up a prompt to confirm whether it allows communication.

Under what circumstances can you consider turning off the firewall?

If you have other third-party firewalls or antivirus software and are familiar with their configuration, you can consider turning off the firewall that comes with Windows to avoid conflicts.

• Certain professional software (such as development environments, virtual machines) may be accidentally blocked by the firewall. Temporary closing of the firewall can help troubleshoot problems.
• When technicians debug network connections, they will also choose to temporarily close the firewall to determine whether it is a problem caused by firewall rules.

But note: Remember to re-activate it after closing , otherwise it will leave safety hazards.

How to turn on or off the firewall correctly?

The operation is actually not complicated, but many people cannot find the correct entrance. The following are the specific steps:

• Open Control Panel → Windows Defender Firewall
• Click "Enable or Turn off Windows Defender Firewall" on the left
• You can set the status of "private network" and "public network" respectively
• Check "Close Windows Defender Firewall" to disable

Tip: If you are using the Home version of Windows 10 or 11 and do not have a Group Policy Editor, you can only operate through this interface.

Simple optimization suggestions

Although the default settings are enough, a little adjustment of the rules can make the firewall more in line with your usage habits:

• You can customize inbound/outbound rules and restrict specific programs from being connected to the Internet (such as prohibiting automatic updates of a certain game)
• For those who often travel on business or change network environments, it is recommended to set up different firewall policies for different network types.
• If you find that some applications suddenly cannot connect to the Internet, check whether the firewall has interception records first

Basically all that is it, the operation is not difficult but the details are easy to ignore. Deciding whether to enable it based on your own usage needs is more important than blindly pursuing "turn off and save trouble".
