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

Как заблокировать несколько файлов в Брандмауэре Windows?

Фаервол – это программное обеспечение или аппаратное средство, которое выполняет проверку входящей информации из Интернета или сети, и либо блокирует ее, либо позволяет проходить через компьютер, в зависимости от настроек самого firewall.

Фаервол может помочь пользователям уберечься от нападения хакеров или от вредоносного программного обеспечения, которые могут получить доступ к вашему компьютеру через вашу сеть. Фаервол также может помочь остановить отправку вредоносных файлов с вашего компьютера на другие ПК.

Все вышеописанное также можно отнести и к Брандмауэру Windows. Некоторые приложения требуют для себя подключения к сети время от времени. Однако, у фаервола есть контроль над тем, какие .exe и .dll на вашем компьютере подключать к публичной, личной или доменным сетям.

По умолчанию, все приложения заблокированы Брандмауэром. Если какому-то приложению или программе запрещено связываться с сетью, то Брандмауэр блокирует ей доступ. В список этих программ также могут входить и ваши игры, для работы с которыми вам требуется Интернет-подключение.

Для того чтобы установить нужные вам настройки в Брандмауэре Windows, вы можете:

• Нажать одновременно кнопки Win+R.
• Затем вписать в строку утилиты «Выполнить» запрос firewall.cpl и нажать Enter.
• Выбрать «Разрешение взаимодействия с приложением или компонентом в брандмауэре Windows».

В этом окне вы сможете выдавать разрешения определенным программам или же добавлять новые исполнительные файлы.

Однако, когда вам нужно заблокировать или снять блокировку с более чем одного исполнительного файла на вашем компьютере(или если вы разрабатываете приложение, которому требуется разрешение firewall’а), то вам нужно проделывать достаточно много однообразной работы для этого.

Сейчас мы покажем вам, как блокировать несколько файлов одновременно или даже целые папки в Брандмауэре Windows. Для демонстрационных целей, мы будет показывать этот метод на папке Program Files.

Для начала вы рекомендуем вам сделать резервную копию вашей политики в Брандмауэре Windows, на случай того, если что-то пойдет не так. Для этого сделайте следующее:

• Нажмите комбинацию из Win+R, напишите wf.msc и нажмите Enter для открытия Брандмауэра Windows в режиме повышенной безопасности.
• В самом правом углу окна, нажмите на «Экспортировать политики…» и сохраните их в файл. Если что-то произойдет при выполнении нижеуказанных шагов, то вы сможете использовать этот Wfw-файл для восстановления состояний политик.

Блокировка нескольких .exe-файлов с помощью BAT-файла

Через netsh(скриптовый инструмент, которые позволяет Командной строке изменять настойки сетевого подключения), вы можете использовать силы Командной строки изменить настройки вашего Firewall’а. Так как Брандмауэр контролирует входящие и исходящие соединения, то вы должны отключить их обоих для ваших файлов. Для этого сделайте следующее:

Откройте Блокнот и копируйте следующие строки в него:

for %%G in (“C:\Program Files (x86)\Test Folder\*.exe”) do (netsh advfirewall firewall add rule name=”Blocked With Batchfile %%G” dir=in action=block program=”%%G” enable=yes profile=anynetsh advfirewall firewall add rule name=”Blocked With Batchfile %%G” dir=out action=block program=”%%G” enable=yes profile=any)

• Чтобы разрешить заблокированные файлы, просто замените значение action=block на значение action=allow.
• Чтобы разрешать или блокировать dll-файлы, найдите в скрипте *.exe и замените ее на *.dll.
