在网络威胁和网络犯罪数量不断增加的今天，在您的计算机上使用防火墙^(firewall)变得极为重要。每当您的计算机连接到Internet甚至任何其他网络时，它都容易受到未经授权的访问的攻击。因此^(Therefore)，您的Windows计算机具有内置的安全系统，称为Windows 防火墙^{(Windows Firewall)}，通过过滤掉进入您系统的任何不需要或有害的信息并阻止可能有害的应用程序，以保护您免受任何未经授权的访问您的计算机。默认情况下，Windows 允许其自己的应用程序通过防火墙。这意味着防火墙对这些特定应用程序有例外，并允许它们与Internet通信。

当您安装新应用程序时，该应用程序会将其例外添加到防火墙以访问网络。因此，Windows会通过“ ^(Windows)Windows安全警报”提示询问您这样做是否安全。

但是，有时您需要手动向防火墙添加一个例外，以防它没有自动完成。您可能还需要对您之前拒绝此类权限的应用执行此操作。同样，您可能希望手动从防火墙中删除例外，以防止应用程序访问Internet。在本文中，我们将讨论如何阻止或允许应用程序通过 Windows 防火墙。^{(block or allow apps through the Windows Firewall.)}

Allow or Block Apps through the Windows Firewall

In theѕe days of elevated nυmbers оf cyber threats and cybercrimеs, it has become extremely important to use a firewall on your computer. Whenever your computer is connected to the Internet or even any other network, it is prone to attacks through unauthorized access. Therefore, your Windows computer has a built-in security system, known as Windows Firewall, in order to protect you against any unauthorized access of your computer by filtering out any unwanted or harmful information entering your system and blocking potentially harmful apps. Windows allows its own apps through a firewall by default. This means that the firewall has an exception for these particular apps and will allow them to communicate with the Internet.

When you install a new app, the app adds its exception to the firewall in order to access the network. Therefore, Windows asks you if it is safe to do so through the ‘Windows Security Alert’ prompt.

However, sometimes you need to add an exception to the firewall manually in case it hasn’t been done automatically. You might also need to do so for apps that you had denied such permissions previously. Similarly, you may want to remove an exception from the firewall manually in order to prevent an app from accessing the Internet. In this article, we will discuss how to block or allow apps through the Windows Firewall.
