每次更新时， Microsoft^(Microsoft)都会向 Windows 添加新的安全功能。Windows 11/10具有最高级的安全功能。防火墙^(Firewall)设置构成了安全功能的关键，但是，有时防火墙会阻止^(Firewall)Windows 11/10上最喜欢的应用程序。

内置防火墙通常可以正常工作并阻止所有恶意应用程序并允许合法应用程序。但在某些情况下，用户需要控制并允许他们的应用绕过防火墙。在我们开始之前，我想建议您在将应用程序列入防火墙白名单之前仔细检查它是否合法。在本部分中，我们将引导您完成几个步骤，这些步骤将帮助您允许或拒绝Windows 防火墙^{(Windows Firewall)}上的某些应用程序。

允许^(Allow)或阻止Windows 11/10 防火墙中的程序^(Firewall)

我们将了解如何在 Windows 11/10 的内置 Windows 防火墙中将程序或应用程序列入白名单、Windows 11/10、取消^{(Windows Firewall)}阻止^(Program)或阻止^(App)。您可以单独将应用程序列入黑名单或白名单，也可以阻止Photoshop等程序访问Internet。

首先，打开Windows Defender 安全中心。选择防火墙^{(Select Firewall)}和网络保护^{(Network Protection)}。

现在点击“允许应用程序通过防火墙^{(Allow an app through firewall)}”。

点击“更改设置^{(Change Settings)}”按钮。确保您具有管理权限

从菜单中选择^(Select)您希望允许通过防火墙^(Firewall)的应用程序。您也可以使用“添加应用程序^{(Add an App)}”选项手动添加应用程序。

现在选择应用程序可以访问的网络类型。

• 专用网络^(Network)将允许应用程序仅在家里或工作场所连接到互联网
• 公共网络^{(Public Network)}将允许应用程序从任何地方连接到互联网，包括公共 WiFi^{(Public WiFi)}热点

单击确定。

为了从防火墙中将应用程序或服务列入黑名单，您需要做的就是取消选中该应用程序的勾选标记，并确保您拒绝对相同的网络访问。在许多情况下，此特定功能非常有用。例如，您可以将您的银行应用程序设置为仅在专用网络^{(Private Network)}中工作，从而保护自己免受公共或不安全WiFi的安全缺陷。这可以帮助您阻止应用程序访问互联网。

管理员还可以对单个应用程序进行更改，这基本上应该反映在所有其他受限用户帐户上。这似乎也是禁止您孩子帐户中的某些应用访问网络的好方法。总而言之，在处理异常或更改防火墙设置时要非常小心，如果操作不当，您的 PC 将容易受到攻击。

How to allow or block a program in Windows Firewall of Windows 11/10

Microsoft has been adding new security features to Windows with every update. Windоws 11/10 comes with superlative sеcurity features as opposed to the earlier versions of the software. Firewall settings form the crux of the security feature, howevеr, sometimeѕ it so happens that the Firewall blocks оut a faνorite app on Windowѕ 11/10.

The inbuilt firewall usually works just fine and blocks out all the malicious apps and allows legit apps. But in some cases, users need to take control and allow their app to bypass the firewall. Before we begin, I would like to advise you to carefully check whether an app is legit before whitelisting it on the firewall. In this segment, we will walk you through several steps that will help you allow or deny certain apps on the Windows Firewall.

Allow or block a program in Windows 11/10 Firewall

We will see how to whitelist, allow, unblock, or block a Program or App in the built-in Windows Firewall of Windows 11/10. You can blacklist or whitelist apps individually or block a program like Photoshop too from accessing the Internet.

First things first, open the Windows Defender Security Center. Select Firewall and Network Protection.

Now click on “Allow an app through firewall”.

Click on “Change Settings” button. Make sure you have administrative privileges

From the menu Select the app that you want to allow through the Firewall. You can also add the app manually by using “Add an App” option.

Now select the type of network an app can access.

• Private Network will allow the app to connect to the internet only at home or work
• Public Network will allow the app to connect to the internet from anywhere including Public WiFi hotspots

Click on OK.

In order to blacklist an app or a service from the firewall all you need to do is uncheck the tick mark against the app and also make sure you deny network access to the same. This particular feature is extremely useful in many cases. For example, you can set your banking app to work only in Private Network and thus safeguard yourself from the security shortcomings of a public or unsecured WiFi. This can help you block an application from accessing the internet.

Admins can also make changes for individual apps and this should essentially reflect on all the other limited user accounts. This also seems to be a good way to ban certain apps on your kid’s account from gaining access to the network. All said and done, be very careful while handling exceptions or changing firewall settings, if not done properly it will leave your PC vulnerable to attacks.
