By Mitch Bartlett 15 Comments

In Microsoft Windows 10 you can set the Windows Defender Firewall to block or unblock certain applications. Here’s how.

1. Select the “Start” button, then type “firewall“.
2. Select the “Windows Defender Firewall” option.
3. Choose the “Allow an app or feature through Windows Defender Firewall” option in the left pane.
   
4. Unchecking the box to the left of the application name disallows it from accessing network resources, while checking it allows access. You can also check the boxes to the right of the name labeled “Private” or “Public” to allow and disallow the app on private or public networks respectively.
   
5. If the program you wish to block or unblock is not listed, you can click the “Allow another app…” button to add it. Choose the application in the list and select “Add“. If the program is not in this list, use the “Browse…” button to select the program file manually.

No…I am definitely not a pro…so a little more explanation would be great…say, what about gallery or settings….?

Susan Olon says

Could you give me an example as to what applications should NOT cross the firewall??

Any application can block any crack microsoft office .. can you help me how to block any crack microsoft on my laptop ..

Richard Jordan says

The firewall is blocking access to open areas of the United Nations website. Even public press releases. How do I uninstall Micrsoft Edge, if that is what is blocking me.

So, what’s the meaning of a checked box and an unchecked box?
I am trying to allow zoom to have access but firewall is blocking it.

I’m trying to block Microsoft family features so it won’t send me the annoying pop-ups about signing in.

I’m on the correct thing but I can’t uncheck the box beside it. If I click the box it does nothing,

Do we have any registry settings for the same.

Thanks, it worked

What if when you click “Allow another app” and then Choose the app in the directory and it gives an error about a possible virus?

Josh Everett says

Is there any way to do this without Administrator rights?

Settings for some pro, doesn’t change!
its somehow locked, as if a registry rule is overriding this windows rules.

Richard S Nye says

I have been trying for hours to Block “Fortnite” from my PC windows 10

Edwin Wetzel says

nothing helps. i’ve been trying to hook up my wifi scanner and i’ve been doing this for hours without any success. i’ve followed all the different procedures on line including going into the defender advanced settings and allowing file and printer sharing rules and still does not work.

What if you cant click the “Allow the app or feature through windows defender firewall”?

Mike Bading says

Mitch,
First, I hope this note finds all well with you and yours.
Second, thank you for your effort here.
Third, my question(s):
What do you do when Windows Defender keeps resetting Microsoft Apps you have unchecked/deselected in Windows 10 Home or Windows 10 Pro?
Example: Let’s say I wish to block Cortana (or any other app). I then follow your instructions here and uncheck/deselect all the boxes pertaining to Cortana and then close the window.
Let’s say, that for whatever reason(s), I return to the window in your example only to find that Windows has reset/unblocked Cortana without notice and without my permission. This would happen all the time in Win10Home; and I would like to know if this would happen in Win10Pro and what to do about it if it does.

Respectfully,
Mike Bading

Windows Firewall: блокировка доступа в Интернет, исходящего и входящего трафика

В статье мы рассмотрим, как заблокировать входящий или исходящий Интернет трафик любому приложению с помощью Windows Firewall . Современную жизнь трудно представить без соединения с интернетом. Все мобильные телефоны, планшеты, компьютера и ноутбуки постоянно взаимодействуют между собой в рамках локальной сети или получают, и отправляют информацию в Интернет. Как бы мы не зависли от сети, в определенных случаях необходимо заблокировать доступ в Интернет некоторым приложениям .

Для чего это может понадобится? Блокировка входящего трафика позволяет отключить не нужные обновления ПО, назойливую рекламу или экономить трафик. Блокировка исходящего – может предотвратить распространение конфиденциальной информации. Возможно вы захотите ограничить вашего ребенка от просмотра нежелательного контента или чрезмерного проведения времени за онлайн играми. В статье мы рассмотрим, как заблокировать входящий или исходящий трафик любому приложению с помощью Windows Firewall. Это наиболее простой и одновременно гибкий способ блокировки доступа.

Мы рассмотрим работу фаервола в Windows 10, однако эта инструкция будет работать и для пользователей Windows 8 или 7.

Создание правила брандмауэра Windows

Для начала необходимо запустить расширенный интерфейс межсетевого экрана. Для этого перейдите в панель управления, выберите режим отображения крупные значки и кликните «Брандмауэр Windows» . Панель управления можно вызвать, кликнув правой кнопкой мышки по кнопке Пуск и выбрав нужный пункт меню, или нажать Пуск и затем ввести Панель управления . В окне брандмауэра нужно кликнуть на Дополнительные параметры .

Расширенный интерфейс брандмауэра содержит множество настроек. Вносите все изменения максимально внимательно, в точности следуя этой инструкции. Не правильная настройка приведет к множеству проблем в работе компьютера.

В левой навигационной панели выберите «Правила для исходящего подключения» . Система отобразит все созданные ранее правила, не удивляйтесь, что список заполнен десятками различных записей, созданных Windows.

В правой панели кликните на «Создать правило» .

По умолчанию предлагается создать правило для программы, подтвердите выбор нажав кнопку Далее .

На следующем шаге необходимо указать путь к исполняемому файлу программы для блокировки. На примере браузера Opera мы проверим блокировку подключения к интернету. Вы можете как внести полный путь к exe файлу вручную, так и воспользоваться кнопкой Обзор .

В последнем случае система автоматически заменит часть пути файла на переменную окружения. В нашем случае файл находится по адресу C:\Program Files\Opera\45.0.0.255225846\opera.exe , но брандмауэр автоматически заменяет путь на %ProgramFiles%\Opera\45.0.0.255225846\opera.exe .

Важно : По ряду причин переменные окружения могут неправильно определяться системой. Если вы столкнулись с тем, что созданное правило блокировки не работает – отредактируйте правило, вставив полный путь к файлу в поле ввод вручную.

Тоже важно : В большинстве случаев достаточно заблокировать исполняемый файл программы, для ограничения доступа к интернету. Но этот подход может не сработать для онлайн игр. К примеру, если вы хотите заблокировать возможность подключения к игровым серверам Minecraft, блокировать нужно приложение Java (исполняемый файл Javaw.exe). Так как игра подключается к сети Интернет через Java.

Подтвердите выбор файла нажав кнопку Далее .

На следующем шаге подтвердите выбор «Блокировать подключение» нажав кнопку Далее .
