How do I fix the Windows Defender 0x80070643 error?

1. Use antivirus removal tools

When you uninstall a third-party antivirus using the Uninstall option from Control Panel, some files might remain undetected, preventing you from running and updating Windows Defender.

Even if you uninstalled your previous antivirus and have been using Windows Defender for quite some time without any problems, you’re not safe.

The remnants of your previous antivirus may now be causing the 0x80070643 Windows Defender error, and since they are hard to remove manually, you need to deal with them some other way.

This is where uninstaller software comes in handy to remove your antivirus or any leftover files. It is specially designed to remove the selected application and all its files and registry entries, leaving a clean space.

Completely uninstall your old antivirus programs, restart your computer, and Windows Defender should be able to install the latest updates.

2. Check your system files

1. Press Windows Key + X and choose Command Prompt (Admin) from the menu.
2. You can also use PowerShell (Admin).
   
3. Type the following command and hit Enter: sfc /scannow
   

The System File Checker tool repairs corruption in system files. Use this tool to verify whether Windows Defender is corrupted, which could explain why you can’t install the updates.

To perform an SFC scan, you need to do the following:

If you can’t run the SFC scan or if SFC didn’t solve the problem, you might have to use a DISM scan instead. To do that, follow these steps:

2. Now run the following command and press Enter: DISM /Online /Cleanup-Image /RestoreHealth
   
3. DISM scan will now start.
4. Remember that this scan can take up to 20 minutes or more, so don’t interrupt it.

Once the DISM scan is finished, check if the problem is resolved. If the issue persists, or if you couldn’t run an SFC scan before, try rerunning the SFC scan and check if that solves the problem.

9. Once you disable all startup applications, close Task Manager and return to the System Configuration window.
10. Click Apply and OK to save changes and restart your PC.
    
11. Once your PC restarts, check if the problem still appears.
    • If not, go back and enable disabled apps and services one by one until you find the one causing the issue.

Вы зашли в центр обновления Windows 10, а там написано:

С установкой некоторых обновлений возникли проблемы…

• Обновление определения для Windows Defender — КБ2267602 (Определение 1.215.422.0) — ошибка 0x80070643

Коды ошибок могут быть разными: 0x80200056, 0x80070002, 0x80070005 и другие

Если заново нажать «обновить», то уже ничего не пишет о Защитнике, а просто пишет «Устройство обновлено». Но если через пару дней зайти в центр обновлений, то там снова появится надпись про ошибку обновления определений.

Если зайти в сам Защитник, то в статусе обновления написано «Ошибка подключения». При попытке обновить появится окно «Не удалось обновить определения вирусов и 

программ-шпионов

. Код ошибки: 0x80070002».

Я с такой проблемой столкнулся в Windows 10, но для предыдущих версий решение такое же.

Решение 1 (сперва попробуйте его)

Идея: Защитник во время обновления пытается удалить временную папку, но ему для этого не хватает прав. Решение: удалить содержимое временных папок.

Для этого:

1. Откройте командную строку от имени администратора (как это сделать?)
2. Скачайте скрипт fix.cmd и запустите его через командную строку. Или можете сами копировать по одной команде, вставлять в командную строку и запускать.
3. После этого зайдите в Центр обновлений → Проверить наличие обновлений. Затем откройте Защитник Windows и обновите определения уже через него.

Решение 2 (если предыдущее не сработает)

Идея такая же: Защитник не может получить доступ к своей собственной папке. Значит нам нужно эту папку удалить, и при следующем запуске Защитник сам ее создаст заново, уже с нужными правами доступа.

Итак:

1. Для удаления папки Защитника, нужно его полностью отключить:
1. Отключаем Защитник в настройках (все переключатели на Выкл).
2. Качаем NoDefender, запускаем, следуем инструкциям.
3. Качаем и устанавливаем Winaero Tweaker (portable или обычная установка — без разницы). Запускаем, набираем в поиске defender или в левом меню ищем снизу раздел Windows Apps → Disable Windows Defender. Нажимаем «Disable Windows Defender».
2. Удаляем папку C:ProgramDataMicrosoftWindows Defender. Кто боится удалять — можно просто переименовать ее. Возможно после этого шага стоит перезагрузить компьютер.
3. Включаем Защитник заново. Сперва в тех двух прогах, затем в настройках. Так же
   через Winaero Tweaker можно вернуть иконку Защитника в трее (если она
   пропала).
4. Вероятно стоит еще раз очистить все временные папки (как написано в Решении 1).
5. Теперь обновите Защитника — все должно получиться.

Заключение

В Windows так же есть средство устранения неполадок с обновлениями. Проблему с Защитником оно, увы, не исправляет. Но на всякий случай запустите его:

1. В Пуске наберите «Поиск и устранение неполадок Центра обновления Windows» → Запустите → Везде нажимайте Далее.
2. Перезагрузка.
3. Откройте Центр обновлений и нажмите Обновить.

Просьба

Этот пост я пишу через несколько недель после самого исправления. Некоторые детали у меня спутались. Например, не помню, что нужно сперва запускать: NoDefender или Winaero Tweaker. Так же не помню в какой момент нужно перезагружать комп — а может и вообще без перезагрузок можно обойтись?

Если вы пытались решить проблему и у вас получилось или нет, то напишите в комментариях об этом. Может быть в 

каких-то

пунктах пришлось делать то, что у меня не указано?
