Одной из наиболее часто встречающихся проблем, с которой сталкиваются пользователи Windows при попытке обновить операционную систему, является ошибка 0x800705b4. Она может возникать на разных этапах обновления, мешая пользователю получать последние исправления безопасности и улучшения функционала системы.
В этой статье мы рассмотрим основные причины возникновения ошибки 0x800705b4 и предложим несколько проверенных способов её устранения.
Ошибка 0x800705b4 в Windows обычно возникает в процессе скачивания или установки обновлений операционной системы. Она может проявляться в разных контекстах, но чаще всего связана с тем, что система не может завершить операцию обновления.
Причиной могут быть различные факторы, включая проблемы с интернет-соединением, повреждённые системные файлы или некорректные настройки безопасности.
- Проблемы с интернет-соединением. Загрузка обновлений требует стабильного и быстрого интернет-соединения. Если соединение нестабильно или слишком медленное, это может привести к сбоям в процессе обновления.
- Повреждения в системных файлах. Если важные системные файлы Windows повреждены, это может повлиять на работу службы обновлений.
- Стороннее ПО. Некоторые сторонние антивирусные программы или брандмауэры могут блокировать процесс обновления.
- Перегрузка системы. Если во время обновления система работает с несколькими ресурсоемкими задачами, это может вызвать ошибку.
Существует несколько эффективных способов устранения ошибки 0x800705b4, начиная со стандартных методов диагностики и заканчивая более сложными шагами. Рассмотрим наиболее распространенные методы.
Прежде всего, всегда стоит начать с перезагрузки компьютера. Это простой, но эффективный способ избавиться от временных сбоев, которые могут мешать процессу обновления. После перезагрузки система может завершить оставшиеся процессы и, возможно, успешно загрузить и установить обновления.
Windows предоставляет встроенное средство для диагностики и устранения проблем с обновлениями. Чтобы воспользоваться им, выполните следующие действия:
Откройте «Параметры» (нажмите Win + I).
Перейдите в раздел «Обновление и безопасность».
Выберите Устранение неполадок, затем кликните «Дополнительные средства устранения неполадок».
Найдите «Windows Update» и нажмите «Запустить средство устранения неполадок».
Это средство выполнит диагностику и попытается устранить выявленные проблемы, которые могут препятствовать нормальной установке обновлений.
Если стандартные методы не помогли, можно вручную сбросить компоненты обновлений Windows. Для этого потребуется несколько команд в командной строке с правами администратора. Вот что нужно сделать:
Откройте командную строку от имени администратора. Для этого нажмите правой кнопкой мыши на кнопку «Пуск» и выберите «Командная строка (Администратор)».
Введите следующие команды по очереди и нажимайте Enter после каждой:
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:\Windows\System32\catroot2 catroot2.old
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
net start cryptSvc
net start bits
net start msiserver
net start wuauserv
Перезагрузите компьютер и попробуйте снова выполнить обновление.
Эти команды остановят службы обновления, переименуют каталоги: catroot2, SoftwareDistribution, отвечающие за скачивание обновлений, затем перезапустят службы и создадут каталоги снова.
Системные файлы могут быть повреждены, что также является одной из причин возникновения ошибки 0x800705b4. В этом случае помогут встроенные утилиты для восстановления:
Откройте Командную строку от имени администратора.
Введите команду для проверки целостности системных файлов: sfc /scannow
Утилита SFC (Проверка системных файлов) выполнит проверку файлов и восстановит повреждённые.
Если ошибка сохраняется, используйте утилиту DISM (Deployment Imaging Service and Management Tool):
DISM /Online /Cleanup-Image /RestoreHealth
Эта команда поможет восстановить повреждения, связанные с образом системы.
Некоторые сторонние антивирусные программы могут блокировать или препятствовать установке обновлений. Временно отключите антивирус или брандмауэр и попробуйте выполнить обновление ещё раз. Если это помогло, вы можете добавить исключения для Центра обновления Windows в настройках антивируса или обновить сам антивирус до последней версии.
Если ни один из вышеперечисленных способов не помог, можно воспользоваться средством создания установочного носителя от Microsoft. Это позволит загрузить и установить обновление Windows 10 или Windows 11 вручную с помощью установочного носителя — ISO образа операционной системы:
Перейдите на сайт Microsoft чтобы скачать Windows 10 или 11. Скачайте и запустите Средство создания установочного носителя. Следуйте инструкциям по созданию загрузочной флешки или DVD-диска и используйте их для обновления системы.
Ошибка 0x800705b4 в Windows может быть вызвана различными проблемами, от нестабильного интернет-соединения до повреждения системных файлов. Применяя пошаговые методы, такие как использование средства устранения неполадок, сброс компонентов обновлений или проверка системных файлов, вы сможете устранить эту ошибку и вернуться к нормальной работе системы. Если проблема продолжает возникать, то прочтите нашу более подробную сттаью на эту тему устранения неполадок Центра обновлений Windows.
Не забывайте регулярно обновлять систему, чтобы обеспечить её стабильную работу и защиту от угроз.
Both Windows 11 and Windows 10 display an update error 0x800705b4 when a system update fails to install. If this error has occurred on your system and you can’t install available updates, apply a few fixes and your issue should be resolved. We’ll show you various ways to get around this problem on your computer.
A few reasons your software update fails to install are that your third-party antivirus or firewall is blocking the update, Windows Update is experiencing issues, your operating system files are corrupted, a third-party app is interfering, and more.
Restart Your PC
One quick way to fix many minor system glitches is by rebooting your PC. These glitches might be why your update isn’t installing, and resolving these issues will fix your update problem.
Make sure to save your unsaved work before turning off your computer.
- Open the Start menu using the Windows key or by selecting the menu icon.
- Select the Power icon in the menu.
- Choose Restart to turn off and back on your computer.
Turn Off Third-Party Antivirus and Firewall on Your PC
If you’ve installed a third-party antivirus or firewall on your PC, that program might be interfering with Windows Update, causing the feature not to install available updates. In this case, temporarily turn off the program to fix the issue.
You’ll find the option to disable the antivirus and the firewall on the main panel of the program. Then, try to install the available updates. You can turn the protection back on after installing the latest updates.
Note that you don’t have to turn off your protection if you use Microsoft Defender Antivirus or Microsoft Defender Firewall. Both these items don’t interfere with Windows Update.
Change How the Windows Update Service Starts
The Windows operating system runs a background service called Windows Update to find and install the latest system updates. It’s possible this service isn’t running correctly, causing your issue.
You can get around that by forcing the service to start automatically with a delay on your PC’s boot.
- Open the Start menu, find Services, and select the item with that name.
- Find Windows Update, right-click the service, and select Properties.
- Open the General tab, select the Startup type drop-down menu, and choose Automatic (Delayed Start).
- Select Apply, choose OK, and close the Services window.
- Restart your PC and try to install the available updates.
Use the Windows Update Troubleshooter
Microsoft has included a Windows Update troubleshooter in both Windows 11 and Windows 10 to allow users to find and fix various update problems. Utilize this tool and let Windows help you resolve any update-related issues.

Disable Other Updates When Updating Windows
Windows updates other Microsoft products when you install system updates. It’s possible one or more of these products are faulty, causing the main system updates not to install.
In this case, isolate those products’ updates by turning off an option in Windows Update settings.
- Open the Start menu, search for Windows Update settings, and select the item with that name.
- Select Advanced options.
- Turn off Receive updates for other Microsoft products (Windows 11) or Receive updates for other Microsoft products when you update Windows (Windows 10).
- Try to install the available updates.
Fix Windows’ Corrupted System Files
Windows Update is a system feature and this feature relies on various core operating system files to function. If those core files are corrupted or damaged, the feature can stop working. This might be the case with your PC.

- Open Start, find System Configuration, and launch the tool.
- Access the Services tab, activate Hide all Microsoft services, and choose Disable all.
- Open the Startup tab and select Open Task Manager.
- Right-click each app that displays Enabled in its Status column and choose Disable.
- Close Task Manager, return to System Configuration, and select Apply followed by OK.
- Restart your PC and try to update your system.
Reset Windows Update
If the Windows Update feature itself is experiencing problems, reset the feature’s various components to possibly fix your issue. You can use a reset script to reset the feature.
- Launch a web browser on your PC and download the reset script for your Windows 11 or Windows 10 system.
- Right-click the downloaded file and select Properties.
- Enable the Unblock option and choose Apply followed by OK.
- Right-click the file and select Run as administrator.
- Choose Yes in the User Account Control prompt.
- Follow the on-screen instructions in the reset tool.
Download and Install the Update Manually
If nothing else works, your last resort is to manually download and install the available updates. Microsoft has an online catalog where you can find and download the updates you want for your PC. This method helps you bypass the Windows Update feature’s issues.
- Go to Settings > Windows Update on Windows 11 or Settings > Update & Security > Windows Update on Windows 10 and find the update that’s failing to install. The update name should start with KB.
- Launch a web browser and head over to the Microsoft Update Catalog site.
- Select the search box on the site, type the update name you noted, and press Enter.
- Find the update on the list and select Download next to that item.
- Launch the downloaded file to install the update on your PC.

Case #2: Windows Defender error
Symptoms
Windows system offers users one built-in protection tool – Windows Defender, which is designed to provide real-time protection for your computer. It is one of the useful tools provided by Microsoft and most of the times it works effective as described. It’s freeware that protects the Windows operating system from external threats such as spyware and malware, and it is a good alternative to additional third-party software to protect your computer.
However, no software is completely free from bugs or errors. There are many cases that Windows Defender fails to start or scan the system and gives different error messages. These messages often appear with numeric code such as 0x80070002 and 0x800705b4. 0x800705b4 is one of the most frequently happened errors, and it can cause Windows Defender to stop and show an error message: «Windows Defender couldn’t turn on real-time protection. This operation returned because the timeout period expired. Click Help for more information about the problem. Error code: 0x800705b4».
Reasons behind the error
— Your computer has installed some third-party protection software which is not compatible with Windows Defender. The conflict between these two tools leads to the error.
— The registry is missing or corrupted, system drivers are outdated, or Windows is not updated. There are cases that your computer reports 0x800705b4 because of certain Windows settings are lost.
— Windows is infected by the latest virus or malicious software, making the system unable to use the tool.
The error stops Windows Defender from working properly and facilitates viruses to penetrate the system. Hence, it should be fixed to assure the system remains in a secure environment. A number of solutions can be used to get rid of the error, as the causes vary from user to user. This part gives two most commonly recommended solutions.
Method #1: Disabling third-party antivirus software
Step 1. Disable or uninstall third-party antivirus software temporarily. You can go to the software’s official website to look for detailed instructions.
Step 2. Keep Firewall turned on. If you have both third-party antivirus software and firewall installed on your computer, you should make sure the Windows firewall is enabled.
Click the search box next to the Start button and type firewall. Click «Firewall & network protection» from the search result. Next, on the right part of the window, make sure Firewall is on.
Step 3. Start Windows Defender. Click the search box next to the Start button and type Service. Right-click Services from the search results and choose Run as administrator. In the Services window, locate Windows Defender and set its startup type to Start.
Step 4. Restart the computer to make these settings take effect.

Alternatively, you can delete the key: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender
Step 4. Restart your computer, and Windows Defender should return to normal working status.
Case #3: Autopilot — Preparing your device for mobile management (0x800705b4)
Symptoms
When enterprise IT administrators use Windows Autopilot to deploy new devices, the «Preparing your device for mobile management (0x800705b4)» error usually pops up in the following stages:
During the OOBE (out-of-box experience), when the device tries to connect to Azure AD for registration, the progress bar will stagnate and eventually an error prompt window will pop up.
The device is stuck in the «Preparing device» interface for a long time (usually more than 30 minutes), and finally displays the error code 0x800705b4, which may also be accompanied by an auxiliary prompt of «Unable to connect to organizational resources». If you check the event viewer, you will see «DeviceEnrollment» related records.
This error usually causes the device to fail to complete the automatic configuration or the enterprise policy and application cannot be deployed normally, and manual intervention is required to continue the setup process.
Common causes
According to Microsoft official documents and statistical analysis of hundreds of enterprise deployment cases, this error mainly comes from the following aspects:
Network connection problems (65% of cases): The outbound interception rules of the enterprise firewall are too strict, blocking the necessary Azure AD connection; the proxy server is improperly configured, and the special proxy rules required for Autopilot are not correctly configured; the internal DNS server cannot correctly resolve key domain names; port 443 is accidentally closed or restricted
System time is not synchronized (20% of cases): CMOS battery failure causes BIOS time reset and serious system time deviation; NTP server is unreachable, causing the device to be unable to synchronize with the time server; wrong time zone setting, especially international version devices purchased by multinational companies.
Configuration policy problems (10% of cases): Autopilot configuration file errors, for example, there are conflicting settings in the deployment policy; the registration timeout setting is too short, and the default value cannot adapt to the high-latency network environment; the device hash is not pre-registered, and the new device is not correctly imported into the Autopilot device list.
Other system problems (5% of cases): Windows image is damaged, especially custom deployment images; network drivers of specific hardware manufacturers have problems; local system key services are not running properly.
Windows Autopilot greatly simplifies the deployment process of new devices, but many IT administrators will feel troubled when encountering the «Preparing your device for mobile management (0x800705b4)» error. Below I will introduce several proven solutions in detail to help you solve this problem completely.
Method 1. Comprehensive network connection inspection and repair
Step 1. Perform basic network tests. Connect the device to a mobile hotspot or other unrestricted network, then open the command prompt (administrator) and execute the following commands in sequence. This will help check whether they can be pinged normally and whether the delay is within a reasonable range.
ping login.microsoftonline.com
ping enterpriseenrollment.manage.microsoft.com
ping enterpriseenrollment-s.manage.microsoft.com
Step 2. Test the port connectivity.
Use telnet to test port 443: telnet login.microsoftonline.com 443
If there is no telnet client, you can test it through PowerShell: Test-NetConnection -ComputerName login.microsoftonline.com -Port 443
Step 3. Check whether the proxy server is normal. First, open «Settings» — «Network and Internet» — «Proxy»; then, temporarily turn off the «Use a proxy server» option; try Autopilot registration again.
Step 4. Adjust firewall rules. Open Windows Defender Firewall with Advanced Security and create a new outbound rule to allow connections from the following endpoints. Restart the device after applying the rule.
*.manage.microsoft.com
*.microsoftonline.com
Method 2. Accurately synchronize the system time.
Step 1. Perform basic time synchronization. Open the command prompt as an administrator, and then execute the following commands to force time synchronization:
net stop w32time
w32tm /unregister
w32tm /register
net start w32time
w32tm /resync
Step 2. Check the NTP server configuration.
- Check the current time server configuration: w32tm /query /configuration
- If you need to modify the NTP server: w32tm /config /syncfromflags:manual /manualpeerlist:»time.windows.com,0x8″
Step 3. Verify the time zone. Open «Settings» — «Time and Language» — «Date and Time», and make sure «Set time automatically» and «Set time zone automatically» are both turned on. In addition, you need to manually check whether the time zone matches the actual location.
Method 3. Registry Adjustment to Extend Timeout
Step 1. Back up the current registry. Open the Registry Editor (regedit) and navigate to the path below. Right-click «Export» to back up the current branch.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
Step 2. Create timeout settings. Create a new item «CDJ» under CurrentVersion (if it does not exist), and then create a new DWORD (32-bit) value in the CDJ item and name it «AADJTimeoutInMinutes». Double-click the newly created value and change the value data to 60 (decimal); finally, restart the device for the change to take effect.
Method 4. Complete System Reset and Redeployment.
Step 1. Prepare the installation media. Download the latest Windows image from Microsoft’s official website, make a bootable USB drive, and select the GPT partition scheme.
Step 2. Install the system completely. Boot from the USB drive, press Shift+F10 on the installation interface to open the command prompt, and enter the following command to skip the network connection. Connect to the network after completing the basic installation.
OOBE\BYPASSNRO
Step 3. Re-register Autopilot. After entering the system, connect to the enterprise network, open «Settings» — «Accounts» — «Work or school account», and then select «Sign in only on this device» to start the registration process.
Method 5. Collect logs and analyze them.
Step 1. Collect necessary logs: open the Event Viewer and export the these logs:
Application and Service Logs/Microsoft/Windows/DeviceManagement-Enterprise-Diagnostics-Provider
Windows Logs/System
Step 2. Look for Autopilot specific logs by navigating to the path: %windir%\debug\microsoft\windows\provisioning\autopilot, and then copy all *.log files.
Step 3. Log in to the Microsoft 365 Administrator Center, create a new service request, and upload all collected logs. Provide a detailed description of the error and the solutions you have tried.
Case #4: 0x800705b4 SCCM – This operation returned because the timeout period expired. Error code: -2147023436 (0x800705b4)
The problem
When you encounter the error «This operation returned because the timeout period expired. Error code: -2147023436 (0x800705b4)» while using System Center Configuration Manager (SCCM), it means that an operation was forced to terminate because the preset waiting time exceeded. This error may occur in a variety of SCCM operation scenarios, including but not limited to key management tasks such as software deployment, policy updates, client installation, and inventory collection. The 0x800705b4 error usually exhibits the following typical symptoms:
Client communication failure: The SCCM client cannot establish an effective connection with the management point (MP) or distribution point (DP), especially in large enterprise environments.
Software deployment interruption: The application or update package suddenly stops during the deployment process, and a timeout error is recorded in the log.
Policy retrieval problem: The client cannot obtain the latest management policy in time, resulting in inconsistent configuration.
Inventory collection delay: Hardware or software inventory data cannot be uploaded to the site server on time.
Specific manifestations in the error log: «Failed to get DP locations» and other similar entries appear in the client log (such as LocationServices.log); the CCMExec service may report an operation timeout; client request processing delays are recorded in the management point log.
Common causes:
After analyzing a large number of enterprise cases, we found that the main causes of the 0x800705b4 error include:
Network-related issues (45% of cases): high network latency, such as the network latency between the client and the SCCM server exceeding the operating threshold; bandwidth restrictions or traffic shaping policies on key network links; intermediate firewalls interrupting long-term connections; DNS resolution delays, slow response of name resolution services.
Server performance issues (30% of cases): SCCM server load is too high, CPU or memory resources are insufficient; disk I/O bottlenecks, slow response of database or distribution point storage; SQL Server performance issues, query execution timeout.
Configuration issues (20% of cases): timeout settings are too short, the default timeout value is not suitable for the actual environment; site boundary configuration errors, clients are assigned to inappropriate sites; client settings are not ideal, and parameters such as polling intervals are improperly configured.
Other issues (5% of cases): insufficient client resources, low performance of terminal devices; security software interference, real-time scanning affects communication; WMI is damaged, and there are problems with Windows Management Specifications.
Method 1. Check the network.
Step 1. Perform basic network tests:
First, perform a continuous ping test from the client to the SCCM server for at least 5 minutes to check the average latency and packet loss rate: ping <SCCM server FQDN> -t
Then, test the connectivity of key ports:
Test-NetConnection <SCCM server IP> -Port 80
Test-NetConnection <SCCM server IP> -Port 443
Step 2. Analyze the network path, and you can try two methods:
Perform tracert to determine the network path: tracert <SCCM server FQDN>
Use PathPing to analyze path performance: pathping <SCCM server FQDN>
Step 3. Optimize bandwidth and QoS. Ensure that SCCM traffic has sufficient bandwidth; configure QoS priority for SCCM-related traffic on network devices; consider deploying distribution points (DPs) at remote sites to reduce WAN dependence.
Method 2. Tune server performance
Step 1. SCCM server resource monitoring, you can use Performance Monitor to track key indicators, such as CPU usage, memory availability, disk queue length, and network utilization.
Step 2. Optimize SQL Server.
First, check the maximum memory configuration of SQL Server:
EXEC sp_configure ‘show advanced options’, 1;
RECONFIGURE;
EXEC sp_configure ‘max server memory (MB)’;
Then, optimize the SCCM database index:
USE CM_<site code>
EXEC sp_updatestats;
Step 3. Adjust IIS configuration, including increasing the idle timeout of SCCM-related application pools (for example, adjusting the default 20 minutes to 40-60 minutes); optimize application pool recycling settings.
Method 3. Adjust client communication settings.
Step 1. Adjust the client timeout settings in the client registry. Find CCM in the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\CCM, and then add or modify:
«CcmHttpTimeout»=dword:0000003c (60 seconds)
«CcmHttpsTimeout»=dword:0000003c
Step 2. To modify the client location service timeout, find the path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\CCM\LocationServices, and then set: «LocationServiceTimeout»=dword:0000003c
Step 3. Modify the client policy through the SCCM console, for example, increase the number of policy request retries (the default 3 times can be increased to 5 times), and extend the policy retrieval timeout.
Method 4. Optimize SCCM site configuration.
Step 1. Adjust the site system role. First, check the management point load balancing configuration; then, consider adding additional management points for large sites; and optimize the distribution point content distribution strategy.
Step 2. Optimize boundaries and boundary groups. Make sure that all IP ranges are correctly included in the boundary definition; also check the boundary group and site allocation relationship; and verify the client automatic site allocation logic.
Step 3. Adjust component configuration, for example, modify the number of SMS_EXECUTIVE component threads, adjust the distribution manager (DistMgr) concurrency settings, and optimize software distribution component parameters.
