Microsoft снова выпускает обязательное обновление Windows 10 KB4589212
10 марта 2021 года Microsoft снова начала развертывание обновления Windows 10 KB4589212 (Intel Microcode) на некоторых устройствах. Хотя обновление предназначено для некоторых процессоров Intel, оно также будет доступно для загрузки на ПК с AMD, и его нельзя пропустить. Если вы приостановите обновления сегодня, загрузка начнется автоматически, когда обновления будут возобновлены.
В прошлом году Microsoft заявила, что Windows 10 KB4589212 предназначена только для Windows 10 версии 2004, версии 20H2 (потребительские выпуски) и Windows Server. Обновление также включает все исправления микрокода Intel, которые уже были выпущены для операционной системы.
Пакет обновления, похоже, был обновлен, и есть вероятность, что патч появится для загрузки, даже если он уже установлен.
Как мы уже упоминали в начале, это обновление микрокода процессора Intel, но Microsoft также продвигает его и на процессоры AMD. Обновление не влияет на процессоры других производителей, что означает, что ничего не произойдет, даже если оно будет загружено и установлено на неподдерживаемых процессорах Intel и AMD.
Эти обновления микрокода Intel предназначены для исправления аппаратных уязвимостей, которые также требуют изменения уровня программного обеспечения и прошивки. Обновления микрокода были впервые выпущены для уязвимостей Spectre и Meltdown, которые потребовали многочисленных обновлений безопасности от Microsoft, Intel и OEM-производителей.
Пользователи могут перейти на страницу Центра обновления Windows и проверить наличие обновлений, чтобы загрузить обновления вручную. Вы также можете посетить каталог Центра обновления Майкрософт здесь и найти соответствующие статьи базы знаний.
Другие обновления для Windows 10
Помимо обновления микрокода Intel, Microsoft также опубликовала новое накопительное обновление (KB5000802) для Windows 10 версии 20H2 и NET Framework. В то время как обновление Patch Tuesday включает в себя общие исправления ошибок и оптимизацию игр, последнее обновление для NET Framework устраняет проблему, при которой могло произойти замедление.
Исправлена еще одна ошибка, из-за которой пользователи могли замечать задержку при вводе текста в текстовое поле с включенной проверкой орфографии. Для разработчиков Microsoft заявляет, что исправила сбои Visual Studio при закреплении окна в Visual Studio.
