You need a new app to open this windows defender

В некоторых случаях вы можете столкнуться с тем, что в Windows 11 или 10 может перестать открываться окно с параметрами службу Безопасности Windows. При попытке открыть Windows Security (Windows Defender) через меню Параметры (Settings -> Update & Security -> Windows Security), трей или поиск, появляется окно с предложением выбрать программу для открытия ссылки:

Вам понадобится новое приложение, чтобы открыть эту ссылку WindowsDefender

You’ll need a new app to open this Windowsdefender link

Эта проблемам связана с повреждением встроенного UWP приложения Windows Security, и Microsoft Store не может найти приложение на компьютере для открытия данной ссылки.

Сначала попробуйте сбросить настройки приложения Безопасность Windows. Откройте консоль PowerShell с правами администратора и выполните:

Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage

Команда может вернуть, что приложение Microsoft.SecHealthUI не найдено:

Package was not found.
Windows cannot remove Microsoft.SecHealthUI_1000.22000.1.0_neutral__8wekyb3d8bbwe because the current user does not have that package installed. Use Get-AppxPackage to see the list of packages installed.

Проверьте, присутствует ли на диске каталог с приложением Windows Security:

Get-ChildItem 'C:WindowsSystemApps'|where-object {$_.Name -like "*SecHealth*"}

Как вы видите, это приложение Windows Security находится в папке
C:WindowsSystemAppsMicrosoft.Windows.SecHealthUI_cw5n1h2txyewy
. Проверьте, что эта папка есть на диске, у вас есть к ней NTFS права доступа, и в каталоге хранится манифест приложения (AppxManifest.xml).

Перерегистрируйте приложение Microsoft.Windows.SecHealthUI в Microsoft Store с помощью PowerShell команды:

Add-AppxPackage -Register -DisableDevelopmentMode "C:WindowsSystemAppsMicrosoft.Windows.SecHealthUI_cw5n1h2txyewyAppXManifest.xml"

После этого попробуйте открыть окно параметров Windows Security из меню Параметры.

Если каталог с приложением отсутствует, можно попробовать восстановить его из хранилища компонентов Windows с помощью SFC и DISM:

sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth

Если при запуске Microsoft Defender Antivirus появляется ошибка “Служба работы с угрозами остановлена, перезапустите ее, исправьте ее согласно инструкции.

После системного сбоя, а также некоторых манипуляций с компонентами защиты при открытии службы безопасности Windows, через приложение Параметры или поиск может появиться сообщение «Вам понадобится новое приложение, чтобы открыть эту ссылку Windows Defender». Подобные сообщения указывают на отсутствие на компьютере приложения, которое могло бы обработать данные определенного типа.

Но в этом конкретном случае оно указывает на повреждение встроенного приложения «Безопасность Windows».

Причиной неполадки может стать системный сбой, повреждение файлов приложения вредоносным ПО, наличие багов в обновлениях безопасности, отмечались также случае появления ошибки после удаления стороннего антивируса и принудительной деинсталляции поставляемых вместе с Windows универсальных приложений. В зависимости от характера повреждения, для устранения неполадки применяется один из этих трех способов. Начинать следует с самого простого.

Сброс приложения

Откройте меню Пуск, найдите в списке приложение «Безопасность Windows», кликните по нему правой кнопкой мыши и выберите в меню «Дополнительно» -> «Параметры приложения».

Прокрутив окно с настройками немного вниз, вы увидите кнопку «Сброс». Нажмите ее и подтвердите действие.

Для сброса приложения вы также можете использовать указанную на скриншоте команду в запущенной от имени администратора консоли PowerShell.

Перерегистрация приложения

Если сбросить таким способом приложение «Безопасность Windows» не удается, а команда выдает ошибку, указывающую на отсутствие приложения Microsoft.SecHealthUI, проверьте наличие папки Microsoft.Windows.SecHealthUI_cw5n1h2txyewy в расположении %windir%SystemApps.

Если папка существует, убедитесь, что у вас имеются на нее права доступа, что в ней есть манифест приложения AppxManifest.xml.

Перерегистрируйте приложение, выполнив в запущенной с правами администратора консоли PowerShell команду:

Add-AppxPackage -Register -DisableDevelopmentMode «полный путь к файлу манифеста»

(см. скриншот)

Восстановление приложения из хранилища компонентов

В случае отсутствии положительного результата либо отсутствии самого каталога или файла манифеста пробуем восстановить приложение из хранилища компонентов командой sfc /scannow.

Если SFC выдаст ошибку повреждения хранилища, сначала восстанавливаем последнее командой:

DISM /Online /Cleanup-Image /RestoreHealth

After installing/upgrading to Windows 11, you may notice that the Windows Defender Security settings page can’t be opened. Nothing may happen when you open the Windows Security dashboard, or the following error may occur when you do so:

You'll need a new app to open this windowsdefender link

Look for an app in the Microsoft Store

Also, none of the windowsdefender:// protocol links work. None of the options (“View security dashboard,” “Run a quick scan,” etc.) in the Windows Security tray menu work.

As a result, you’re unable to view the “Virus & threat protection,” “Account protection,” “Firewall & network protection,” and other Windows Defender settings GUI.

The above error happens if the Security Health UI app (SecHealthUI.exe) is broken. The issue can easily be fixed by resetting or reinstalling the Windows Security Health UI app package.

[Fix] You’ll Need a New App to Open This Windows Defender Link

Instructions for Windows 11

Option 1: Repair the Windows Security app

To reset and repair the Windows Security app in Windows 11, open PowerShell elevated (Run as administrator).

Run the following command and hit Enter:

Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage

If you see the “Deployment operation progress:” message and end up with no error message/output, the command was successful. You should be able to launch the Windows Defender security settings dashboard now.

Some users may get the following error instead:

"Reset-AppxPackage : Package was not found.
Windows cannot remove Microsoft.SecHealthUI_1000.22000.1.0_neutral__8wekyb3d8bbwe because the current user does not have that package installed. Use Get-AppxPackage to see the list of packages installed.
At line:1 char:51
+ Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage
+ ~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Reset-AppxPackage], COMException
+ FullyQualifiedErrorId : System.Runtime.InteropServices.COMException,Microsoft.Windows.Appx.PackageManager.Commands.ResetAppxPackageCommand"

The above indicates that the package is not installed for your user account. In that case, (re)installing the Microsoft.SecHealthUI package ought to fix the problem. To do so, run the following PowerShell command:

add-appxpackage -disabledevelopmentmode -register ((Get-AppxPackage Microsoft.SecHealthUI -allusers).InstallLocation + 'AppxManifest.xml')

(The app’s name is “Microsoft.Windows.SecHealthUI“in Windows 10 and “Microsoft.SecHealthUI“in Windows 11.)

add-appxpackage : Cannot find path 'C:AppxManifest.xml' because it does not exist.

Option 2: Reinstall “Windows Security” using the Installer file

The above error occurs if the Microsoft.SecHealthUI package folder is entirely missing. In that case, open the following folder:

C:WindowsSystem32SecurityHealth

In one of its subfolders, locate the file named”Microsoft.SecHealthUI_8wekyb3d8bbwe.appx“.

Suppose the above Appx file is found. Double-click to install it. It launches the App installer screen. Follow the instructions and install the app.

Alternatively, you can use admin PowerShell to install the app if the installer doesn’t start when double-clicking on the file.

Right-click on “Microsoft.SecHealthUI_8wekyb3d8bbwe.appx” and click “Copy as Path”.

Switch to the Admin PowerShell window, and run the following command:

Add-AppxPackage -Path <PASTE THE FILE PATH HERE>

Example:

Add-AppxPackage -Path "C:UsersrameshDesktopMicrosoft.SecHealthUI_8wekyb3d8bbwe.appx"

Download the SecHealthUI Installer

If the SecurityHealth folder is empty and you can’t find “Microsoft.SecHealthUI_8wekyb3d8bbwe.appx” on your Windows 11 (22H2) computer, download it from the following link:

File		: Microsoft.SecHealthUI_8wekyb3d8bbwe.appx (Size:8.23 MB)

The above package requires the following dependencies to be installed. These two dependencies would most likely be installed already on the system, as they’re used by other Inbox apps like Microsoft Store, etc.

• Microsoft.VCLibs.140.00_14.0.30704.0_x64__8wekyb3d8bbwe
• Microsoft.UI.Xaml.2.4_2.42007.9001.0_x64__8wekyb3d8bbwe [Download]

Verify if the Package has been installed correctly

If the installation was successful, you should be able to launch the Windows Security page correctly. Also,  running the windowsdefender:// protocol command via the Start, Run dialog should open the Windows Security dialog.

Running the “Get-AppxPackage *sechealth*” command in PowerShell should show an output like the one below:

Instructions for Windows 10

On Windows 10, the Windows Security app name is slightly different:

add-appxpackage -disabledevelopmentmode -register ((Get-AppxPackage Microsoft.Windows.SecHealthUI -allusers).InstallLocation + 'AppxManifest.xml')

[Windows 10 v21H2]
C:WindowsSystemAppsMicrosoft.Windows.SecHealthUI_cw5n1h2txyewy

[Windows 11 v21H2]
C:Program FilesWindowsAppsMicrosoft.SecHealthUI_1000.22000.251.0_neutral__8wekyb3d8bbwe
(The above folder name would change according to your Windows 11 Build number.)

Add-AppxPackage : Cannot find path
'C:WindowsSystemAppsMicrosoft.Windows.SecHealthUI_cw5n1h2txyewyAppXManifest.xml' because it does not exist.
At line:1 char:1

+ CategoryInfo : ObjectNotFound: (C:WindowsSyst...ppXManifest.xml:String) [Add-AppxPackage], ItemNotFoundException
+ FullyQualifiedErrorId : PathNotFound,Microsoft.Windows.Appx.PackageManager.Commands.AddAppxPackageCommand

As a last resort, running a repair installation (a.k.a, in-place upgrade) by running setup.exe from Windows 11 DVD/USB/ISO should automatically rectify the Windows Security Dashboard. Repair installation is suggested, especially when some built-in apps, such as Calculator, Weather, Notepad, Paint, and Feedback Center, go missing after the Windows 11 upgrade.
