重置Windows防火牆可通過控制面板或命令提示符恢復(fù)默認設(shè)置。 1. 控制面板方法：打開控制面板進入Windows Defender防火牆，點擊“還原默認設(shè)置”並確認操作，此過程清除所有自定義規(guī)則和策略。 2. 命令提示符方法：以管理員身份運行並輸入netsh advfirewall reset命令，該方法同時重置域、專用和公共網(wǎng)絡(luò)配置文件。重置後所有手動添加的規(guī)則和例外需重新配置，系統(tǒng)服務(wù)將自動允許，部分應(yīng)用可能再次提示訪問權(quán)限，建議重置後檢查所需規(guī)則確保安全性。

If your Windows Firewall is acting up or you're troubleshooting network issues, resetting it to default settings can help clear out any conflicting rules or configurations. It's a straightforward process and doesn't require third-party tools — just a few steps in the built-in Windows interface or via Command Prompt.

How to Reset Windows Firewall via Control Panel

This method works for most users who are experiencing general firewall issues or want to start fresh without diving into advanced tools.

• Open Control Panel and go to Windows Defender Firewall
• On the left side, click Restore defaults
• A confirmation window will pop up — click Restore defaults again
• You may be prompted by User Account Control; click Yes to continue

This resets all inbound and outbound rules to their original state and clears any custom policies you've applied. It won't affect your antivirus software, but it might temporarily allow more apps through the firewall until you reconfigure things.

Using Command Prompt to Reset Firewall Settings

If you prefer using the command line (or if the GUI isn't working well), this is a solid alternative.

1. Open Command Prompt as Administrator
2. Type the following command and press Enter:

    netsh advfirewall reset

3. Wait a few seconds for the process to complete — there's no confirmation message unless something goes wrong

This method also resets all firewall rules and profiles to default. One thing to note: it affects all three network profiles — Domain, Private, and Public — so make sure that's what you want before running it.

What Happens After Resetting?

After you reset the firewall, here's what to expect:

• All custom inbound and outbound rules will be deleted
• Any app exceptions you added manually will need to be re-added
• The firewall will automatically allow essential system services again
• You may see new notifications from apps trying to access the internet

It's normal for some apps to ask for permission again after the reset. If you use a third-party firewall, it might still show old behavior until you restart or re-enable it properly.

That's basically it. Either method gets the job done — the Control Panel one is easier for most people, while the Command Prompt version is quicker for those comfortable with terminal commands. Just remember to re-check your allowed apps and rules afterward if you rely on specific firewall settings.
