0x800705b9 ошибка windows 10

Ошибка 0x800705b9 обычно связана с нехваткой системных ресурсов или повреждением системных файлов, которые могут помешать корректной установке обновлений или программ. Ниже приведён ряд типовых шагов, которые помогают решить подобную проблему.


1. Проверьте наличие свободного места и системные ресурсы

  1. Свободное место на системном диске (обычно диск C):
    • Убедитесь, что на диске, куда устанавливаются обновления, достаточно свободного пространства. Для Windows обычно желательно иметь хотя бы 10–15 ГБ свободных.
  2. Отключите антивирусное ПО (если возможно):
    • В некоторых случаях антивирус может блокировать установку компонентов, создавая конфликт.

2. Запустите стандартное средство устранения неполадок Центра обновления Windows

  1. Откройте Параметры → Обновление и безопасность → Устранение неполадок (или Диагностика).
  2. Найдите средство для работы с Центром обновления Windows и запустите его, следуйте инструкциям на экране.

Инструмент автоматически попытается найти и исправить основные ошибки, связанные с обновлениями.


3. Воспользуйтесь встроенными утилитами SFC и DISM

Шаг 1: проверка системных файлов (SFC)

  1. Запустите командную строку (CMD) или PowerShell от имени администратора.
  2. Введите команду:
    
    
  3. Дождитесь окончания проверки. Если будут обнаружены повреждения системных файлов, SFC попытается их исправить.

Шаг 2: восстановление целостности образа системы (DISM)

Если SFC не смог устранить проблемы, попробуйте DISM:

  1. Всё в той же командной строке (CMD) или PowerShell от имени администратора введите команды по очереди (каждая команда может занять несколько минут):

    bash

    DISM /Online /Cleanup-Image /CheckHealth DISM /Online /Cleanup-Image /ScanHealth DISM /Online /Cleanup-Image /RestoreHealth

  2. Перезагрузите компьютер после завершения команд и повторите попытку установки обновления или нужного компонента.

4. Переименуйте папку SoftwareDistribution и Catroot2 (сброс центра обновления)

Иногда центр обновления Windows «запоминает» повреждённые файлы и не может загрузить корректные. Переименование этих папок сбрасывает кеш обновлений.

  1. Откройте командную строку (CMD) от имени администратора и остановите службы:

    bash

    net stop wuauserv net stop bits net stop cryptsvc

  2. Переименуйте папки:

    bash

    ren C:\Windows\SoftwareDistribution SoftwareDistribution.old ren C:\Windows\System32\catroot2 Catroot2.old

  3. Запустите службы обратно:

    bash

    net start wuauserv net start bits net start cryptsvc

  4. Перезагрузите компьютер и повторите попытку установки.

5. Выполните «чистую» загрузку (Clean Boot)

Иногда конфликт программ или служб может вызывать ошибку 0x800705b9.

  1. Нажмите Win+R, введите msconfig и нажмите Enter.
  2. Перейдите во вкладку Службы, поставьте галочку «Не отображать службы Майкрософт» и отключите все остальные.
  3. Во вкладке Автозагрузка (или «Автозагрузка» в Диспетчере задач) отключите все несущественные программы.
  4. Перезагрузите компьютер и попробуйте установить обновление/приложение ещё раз.

Чтобы вернуться к обычному режиму, повторно включите отключённые службы и программы.


6. Дополнительные рекомендации

  • Обновите драйверы: иногда устаревшие драйверы устройств (особенно драйверы чипсета, сетевой карты и пр.) становятся причиной ошибок при установке.
  • Проверьте журнал событий Windows (Event Viewer): он может подсказать дополнительные детали об ошибках (время, компоненты и т.д.).
  • Отключите сторонние программы, особенно оптимизаторы системы: нередко они вмешиваются в процесс обновления.
  • При необходимости выполните «ремонт» системы: в более сложных случаях помогает «обновление Windows с сохранением файлов» (Repair Install), используя установочный носитель Windows.

Если ни один из перечисленных способов не сработал, возможно, есть более специфичная причина для ошибки 0x800705b9 (например, аппаратная неисправность или серьёзное повреждение системы). В таком случае имеет смысл:

  1. Попробовать переустановить Windows с нуля (при условии, что у вас есть резервные копии).
  2. Проверить оперативную память (с помощью инструмента «Проверка памяти Windows» или утилит вроде MemTest86).
  3. При необходимости обратиться к специалисту или в службу поддержки Microsoft.

Надеемся, что один из перечисленных способов поможет устранить ошибку 0x800705b9 и успешно завершить установку!

Fix Windows Update Error Code 0x800705b9

What causes this error 0x800705b9 on Windows?

Windows 11/10 fails to update on an error code 0x800705b9 when your system meets certain conditions as outlined below –

  • Missing or damaged system files
  • Corruption within the System Image
  • Running a third-party Antivirus program
  • Corrupted Windows Cache folders

Now that you know what may cause this error code, let’s explore the workarounds that might help you overcome this issue on Windows 11/10 PCs.

5 Ways to Solve Update Error code 0x800705b9

If you are unable to update Windows 11/10 because of some error code 0x800705b9, we suggest following the below fixes one after another. In case you have already tried these fixes, skip to the last solution i.e. manually download and install pending updates. 

  • Troubleshoot Windows Update
  • Restart all update-related services
  • Disable Third-party Antivirus Programs
  • Purge Windows Cache folders

1] Troubleshoot Windows Update

The most effective way to resolve any update-related issues on Windows 11/10 is by running the troubleshooter. This tool checks for the reasons preventing an update, and resolves them on its own. You may find this tool by navigating to the below path –

Windows 10:

Settings > Update & Security > Troubleshoot > Additional troubleshooters

Windows 11:

Settings > System > Troubleshoot > Other troubleshooters

After you reach out to the above-mentioned path on your respective devices, search for Windows Update under Most frequent. When found, click on it to expand and hit Run the troubleshooter (Windows 10).

Windows Update Troubleshooter

On Windows 11, you need not require clicking on Windows Update. Rather, you will see the Run button available beside Windows Update. Click on it and the troubleshooter begins looking for the reasons blocking pending updates from installing on your computer. 

Windows 11 Update Troubleshooter

After the troubleshooting completes, your device must be ready to install pending updates. Even in cases, where this tool doesn’t resolve the issue, this will guide you to the probable reasons causing an error code 0x800705b9. 

2] Restart all update-related services

For Windows Updates to install successfully, all update-related services must be up and running. In cases where even one service is disabled, you won’t be able to update your operating system. Here’s what you must check and ensure they are running on your Windows 11/10 PC –

  • Press Win + X, and choose Run.
  • Type “services.msc” on it and hit OK.
  • On the Services window, locate Background Intelligent and Transfer service. 
  • When found, right-click on it and select Properties
  • Use the drop-down menu available next to the Startup type, and change it to Automatic
  • Click Apply and then OK, to confirm the recent changes. 
  • Proceeding as guided above, restart the below-mentioned services as well. 
    • Windows Update
    • Cryptographic services
  • Assuming you did start all update-related services on your computer, close the Services window, and restart your Windows PC. 

Sign back into your device and when it does, navigate to the below path.

Win 11: Settings > Windows Update

Win 10: Settings > Update & Security > Windows Update

Head over to the right pane and click Check for updates. Now that all update-related services are up and running, you might succeed in installing pending updates on your PC. 

3] Disable Third-party Antivirus Programs

Though antivirus programs are developed to keep your device safe and secure, they might at times bring more trouble than good. This happens because of their constant interactions with the system files and folders. While modifying the system files, they might corrupt the Update files resulting in an error code 0x800705b9.

You can never be sure of it unless you disable your third-party antivirus program. Do so and check if you can update Windows after uninstalling or temporarily deactivating external security apps.

Note: Windows Security is an in-built security app on Windows 11/10 that you may use instead of relying on free third-party antivirus programs. 

Run SFC/DISM Scans

When you remove an antivirus program, the affected system files are still there and so you won’t be able to update your Windows. Run System File Checker and DISM tools to automatically detect and resolve file corruptions. Here’s how to run both of these tools on Windows 11/10. 

  • Launch CMD as administrator first. 
  • When the UAC window prompts, click Yes to authorize accessing Command Prompt.
  • On the elevated console, execute the below SFC command. 

sfc /scannow

  • This whole checking and repairing process might take 10-15 minutes. So, wait till then patiently.
  • After this SFC scan reaches 100%, run the DISM tool. For that, all you need is to execute the below command on the elevated console –

DISM /Online /Cleanup-Image /RestoreHealth

SFC and DISM Tools on Windows 11 Terminal

  • Wait again for 10-15 minutes while the DISM checks and repairs corruption inside the System Image. 

Restart your PC so that the changes made become effective from the next login. If you are still encountering the error code 0x800705b9, follow the next set of solutions. 

4] Purge Windows Cache folders

Information related to each and every update is logged into Windows Cache folders. Over a period of time, these folders contain more information than they should. Because of this, some files and folders may become corrupt and hence prevent future updates from occurring.

There are two such folders on Windows 11/10 namely – SoftwareDistribution and Catroot2. Purge all the contents inside both these folders, and you might be able to update Windows normally. Before you proceed ahead, make sure to disable all the update-related folders first.

If you are finding it difficult, you may run a few codes on Command Prompt (Admin), and the problem resolves in no time. Here’s what you need to run on an elevated console –

  • Disable all update-related services by running these codes. 

net stop bits
net stop wuauserv
net stop appidsvc
net stop cryptsvc

  • Delete Profile data and rename Windows Cache directories by executing these codes. 

Del “%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\*.*”
rmdir %systemroot%\SoftwareDistribution /S /Q
rmdir %systemroot%\system32\catroot2 /S /Q

  • To re-register the missing or corrupted DLL files, use these codes –

regsvr32.exe /s atl.dll
regsvr32.exe /s urlmon.dll
regsvr32.exe /s mshtml.dll

  • Reset the network and the available proxy on your Windows PC –

netsh winsock reset
netsh winsock reset proxy

  • Restart all update-related services that you had stopped before. 

net start bits
net start wuauserv
net start appidsvc
net start cryptsvc

Restart your PC and check if the error code 0x800705b9 resolves now. I believe it should have. In case it doesn’t, try out the last workaround.

5] Manually install pending updates

If none of the above fixes resolve the error code 0x800705b9, the problem must be complex in nature. Well, in such cases, you need not rely on fixes but rather manually download and install pending updates on your computer. 

Here’s a complete guide on how to manually install pending updates on Windows 11/10 PCs. 

  • Manually install Windows 11, cumulative updates.
  • Manually install Windows 10, cumulative updates.

The manual installation will override any condition or existing rule on your computer. Hence, we say this solution will surely work on Windows 11 or 10 devices.
