Ошибка, которая кажется довольно распространенной, приводит к тому, что служба безопасности Windows показывает сообщение об ошибке «Вам понадобится новое приложение для этой ссылки windowsdefender» в предварительных сборках Windows 11.
Предварительная версия Windows 11 в настоящее время доступна тестировщикам в рамках программы предварительной оценки Windows, и пользователи сталкиваются с различными проблемами и ошибками в разработанной ОС для настольных ПК.
Согласно сообщениям пользователей, Microsoft недавно выпустила ошибочное обновление, которое, похоже, вызывает серьезные проблемы с приложением безопасности Windows, которое используется для управления Защитником Windows и другими функциями безопасности. К счастью, здесь есть простое решение. Поскольку «Безопасность Windows» является системным приложением, его можно исправить с помощью PowerShell.
Windows 11 Build 22000.160 или более ранняя сборка приводит к тому, что служба безопасности Windows отображает сообщения об ошибках, в которых говорится: «Вам понадобится новое приложение для этой ссылки windowsdefender». Хотя пользователи по-прежнему могут просматривать состояние антивируса, брандмауэра и защиты, некоторые из них больше не могут открывать различные функции защиты, такие как защита учетной записи, брандмауэр и защита сети, приложения и управление браузером и т.д.
Я не могу открыть Безопасность Windows на сборке 22000. При попытке сделать это отображается сообщение, предлагающее мне поискать приложение в магазине — написал один пользователь в Центре отзывов.
Исправьте «Вам понадобится новое приложение для этой ссылки windowsdefender» в Windows 11
Чтобы исправить ошибку «ссылка на windowsdefender» в Windows 11, выполните следующие действия:
- Откройте Windows PowerShell из поиска или из меню «Пуск» с правами администратора.
- Скопируйте и вставьте: Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage
- Закройте окно PowerShell.
После этого вы снова сможете запустить приложение безопасности Windows.
Другие известные проблемы в Windows 11
Многие из первых проблем уже были признаны Microsoft.
Например, Microsoft изучает сообщения о проблеме, из-за которой тестировщики в Beta-канале не видят новую панель задач и меню «Пуск». Чтобы решить эту проблему, перейдите в Центр обновления Windows -> Журнал обновлений и удалите последнее накопительное обновление. После удаления патча вы можете переустановить его, проверив наличие обновлений.
Аналогичным образом, Windows 11 страдает следующими проблемами:
- Возможно, вам не удастся ввести текст в окно поиска.
- Панель задач мерцает при переключении методов ввода.
- Приложение Параметры вылетает при использовании поля поиска.
- У устройств Bluetooth LE возникают проблемы со стабильностью Bluetooth.
- Доска виджетов Windows может работать некорректно.
Эти проблемы будут исправлены в ближайшие недели перед выпуском в октябре 2021 года.
