Resetting Windows Firewall settings can restore default rules to ensure system security. 1. Use the command prompt with administrator permissions to execute the "netsh advfirewall reset" command to quickly restore the factory settings without affecting system files and other software, and there is no need to restart; 2. Check the firewall status through the Windows Security Center to confirm whether the firewall of each network type is turned on, which is suitable for situations where only partial adjustments are wanted; 3. After resetting, you need to note that custom rules will be deleted, and third-party firewalls may overwrite settings. It is recommended to take screenshots in advance to save the rule list. Enterprise users may not be able to change due to group policy restrictions.

If the Windows Firewall settings are changed, or you are not sure whether the current configuration is safe, resetting to the default settings is an easy and effective solution. This operation will not affect your system files or other software, it will only restore the firewall rules to the state when the system was just installed.

1. Quick reset using the command prompt

This is the fastest and most recommended method. The administrator permission command prompt can restore the firewall factory settings with one click.

• Open the Start Menu and search for "cmd"
• Right-click "Command Prompt" and select "Run as Administrator"
• Enter the following command and press Enter:

 netsh advfirewall reset

After execution, the system will automatically restore all inbound and outbound rules and policies to the default state. The whole process takes only a few seconds and does not require a restart.

2. Manual inspection through Windows Security Center (suitable for situations where only partial adjustments are desired)

If you don't want to reset completely, but want to confirm that the firewall is enabled normally, you can view it through the graphical interface:

• Open Windows Security Center
• Click "Firewall and Network Protection"
• Check whether the firewall status of each network type is "Open"

While this does not completely reset the rules, it ensures that the firewall itself is in operation. If you have turned off the firewall before, you can turn it on again.

3. What should I pay attention to after resetting?

After resetting, some custom rules you added yourself will be removed, such as exceptions that you once allowed a program to pass through a firewall may need to be reset.

• If you use third-party firewalls or antivirus software, they may overwrite Windows Firewall settings
• It is recommended to take a screenshot before resetting and save the current rule list (you can open advanced settings through wf.msc to view)
• Enterprise users or computers managed by Group Policy may not be able to change settings freely due to policy restrictions.

Basically that's it. Using the command prompt is the most direct way, it is not complicated but it is easy to ignore details, such as running with administrator privileges. If you are not sure what modifications you have made and want the system to return to a "clean" firewall state, resetting is a good choice.
