Способ 1: Проверка даты и времени
Чаще всего с ошибкой 0x800b0101 пользователи сталкиваются, если на компьютере установлены неверные значения даты и времени. В этом случае решение довольно простое – нужно вручную отредактировать эти параметры.
- Используйте сочетание клавиш «Win + R», чтобы вызвать окно «Выполнить», затем введите в поле запрос
timedate.cplи нажмите на кнопку «ОК». - В появившемся окне перейдите на вкладку «Время по Интернету» и кликните по кнопке «Изменить параметры».
- Убедитесь, что в поле «Сервер» установлено значение
time.windows.com. Если нет, тогда выставьте его и подтвердите новые параметры, нажав на кнопку «ОК». - Далее в окне «Дата и время» переключитесь на одноименную вкладку и проверьте часовой пояс, который соответствует вашему региону. Если он неверен, нажмите на «Изменить часовой пояс» и из выпадающего меню выберите нужное значение, сохраните настройки.
- Снова сохраните изменения, нажав на «ОК», если они были внесены.
После потребуется перезагрузить компьютер. Если все дело в сбитых настройках времени, тогда обновление должно завершиться успешно. Также можете обратиться к нашему отдельному материалу с дополнительными способами смены даты и времени на компьютере с Windows 10.

Если через некоторое время параметры снова беспричинно сбиваются, следует заменить батарейку-«таблетку» CR2032, установленную на материнскую плату. Это необходимо сделать потому, что именно она отвечает за правильные дату и время, даже если устройство выключено. С годами она разряжается и базовые параметры ПК, хранящиеся на одном из чипов и зависящие от энергии, сбиваются.

Способ 2: Встроенное средство устранения неполадок
Как правило, ошибка под кодом 0x800b0101 появляется во время обновления операционной системы. Если это происходит при использовании автоматизированного средства «Центр обновления Windows», можно прибегнуть к помощи встроенного инструмента, которое предназначено для поиска и устранения неполадок, связанных с ним:
- Нажмите на кнопку «Пуск» и выберите запуск штатных «Параметров».
- Перейдите в раздел «Обновление и безопасность».
- Далее выберите вкладку «Устранение неполадок» на панели слева, а в основной части окна кликните по строке «Дополнительные средства устранения неполадок».
- В списке найдите строку «Центр обновления Windows», щелкните по ней, затем выберите запуск средства устранения неполадок.
Начнется поиск проблем, которые могут быть причиной появления рассматриваемой ошибки при установке апдейтов через «Центр обновления Windows». В некоторых случаях, в зависимости от характера и причины неполадки, могут потребоваться дополнительные действия со стороны пользователя, где достаточно следовать инструкциям пошагового мастера. В остальных случаях исправление ситуации происходит автоматически.
Способ 3: Утилиты SFC и DISM
При повреждении файловой системы, а именно файлов и их хранилища, и также при обновлении Windows 10 могут появляться различные ошибки, включая 0x800b0101. В операционных системах от Microsoft реализованы специальные утилиты для восстановления целостности системы – SFC и DISM. Применяются они посредством специальных команд, выполненных в консольной оболочке:
- С помощью строки системного поиска найдите консоль «Командная строка», введя соответствующий запрос, затем нажмите на строку «Запуск от имени администратора».
- Вставьте команду
DISM.exe /Online /Cleanup-image /Restorehealthи нажмите на клавишу «Enter». - Следует отметить, что утилита DISM обращается к «Центру обновления Windows» для получения файлов, которые смогут устранить неполадки. Если же поврежден сам компонент («Центр обновления»), тогда придется воспользоваться другой командой, но предварительно нужно создать накопитель с источником восстановления, то есть оригинальным образом Windows. Затем подсоедините его, если это флешка, или используйте привод для оптического накопителя.
Подробнее: Руководство по созданию загрузочной флешки / диска с Windows 10
- Что касается самой команды, то введите следующее:
DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess, где под «C:\RepairSource\Windows» подразумевается ваш путь к источнику восстановления.Уточним, что вам понадобится указать путь до файла «install.wim» или «install.esd», записанного на флешку/диск. Путь определяется так: откройте «Проводник», нажмите ПКМ по флешке или диску и выберите пункт «Открыть в новом окне» — это позволит просмотреть записанные на носитель файлы. Перейдите в папку «sources» и посмотрите формат файла «install» — «.wim» или «.esd». Затем через адресную строку вверху окна скопируйте путь, вернитесь в консоль, вставьте его и допишите название файла «install» с форматом. К примеру, должно получиться:
E:\sources\install.wim - После проверки хранилища программных компонентов также можно использовать утилиту System File Checker для проверки и восстановления целостности системных файлов. Для этого выполните команду
sfc /scannow.
После сканирования закройте «Командную строку» и проверьте, устранена ли ошибка при обновлении через «Центр обновления Windows».
Способ 4: Очистка данных в кеше обновлений
Если ранее были скачаны файлы обновлений, но с ошибками или повреждениями, может происходить конфликт между программными компонентами, поэтому стоит очистить папки с кешем апдейтов. Делается это как вручную, так и с помощью «Командной строки». Так как второй вариант проще, разберем его:
- Запустите консоль «Командная строка» с расширенными правами так же, как было показано ранее. Затем с помощью команд отключите «Центр обновления Windows» и несколько связанных с ним служб, поочередно выполнив следующие команды:
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver - Следующие команды предназначены для изменения имени каталогов с кешем: система создаст новые автоматически, а старые (с припиской «.old») можно будет удалить, если обновление в итоге пройдет успешно. Поочередно введите следующие команды, нажимая после каждой на клавишу «Enter»:
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old - Теперь потребуется запустить службы и сам «Центр обновления Windows», работу которых мы остановили на Шаге 1/ Используйте команды:
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
После того как все процессы, необходимые для автоматического обновления, будут вновь активны, перезагрузите компьютер и выполните повторную загрузку и инсталляцию апдейтов.
Способ 5: Ручное обновление
Если ни один способ не помог, можно попробовать обойти рассматриваемую ошибку, скачав проблемное обновление вручную. Не всегда это позволяет избежать возможных проблем с автоматическими обновлениями в дальнейшем, но в некоторых апдейтах могут содержаться исправления, с помощью которых подобная ошибка не появится вновь.
Чтобы вручную обновить операционную систему, потребуется посетить «Каталог Центра обновления Майкрософт» на официальном сайте этой компании, отыскать проблемный апдейт, скачать его и инсталлировать самостоятельно. Ранее мы писали об этом более детально в отдельном руководстве.

Frequently Asked Questions
Why Should I Install Windows Updates?
If you don’t keep your computer up to date, viruses could be hiding in your system, waiting for a chance to attack. Your operating system may ask you to download security patches when you install new software or update existing programs. These patches are made to keep bad code from getting on your PC.
Is there a way to stop Windows from downloading updates on its own?
Yes! Using Group Policy Editor, you can stop Windows 10 from downloading updates on its own (GPE). You must be an administrator or a member of the local Administrators group to use this method.
Some Windows 10 users are encountering the 0x800b0101 when trying to install a pending update via Windows Update Standalone installer or when trying to install a different Windows component via Windows Installer. This issue seems to be restricted to Windows 10.
After investigating this particular issue thoroughly, it turns out that there are several different underlying causes that are known to cause this particular error on Windows 10. Here’s a list of potential culprits:
- Incorrect Date & Time – As it turns out, if your system has date & time values that are way off the expected equivalents by the security certificate, you might see this error as the connection with the server is terminated. To resolve this problem, you’ll need to change the date & time values of your system to the correct ones.
- Running SFC and DISM scans – System file corruption is also known to trigger this particular error, particularly if you’re experiencing this error code with every pending Windows Update that you attempt to install. In this case, you can get the issue fixed by running SFC and DISM scans and applying the recommended fixes.
- Missing Update Requirements – According to some affected users, you can also expect to see this error code in situations where you are trying to install a pending update for the System Center Configuration manager when a couple of update requirements are missing. In this case, installing the missing updates first (via the Windows Update Catalog) should take care of the issue for you.
- Bad AccountRight installer – In case you are only seeing this error while attempting to install or update AccountRight, chances are you’re dealing with a bad installer package. In this case, downloading the patched installer should take care of the issue for you.
Now that you are familiar with every potential cause of the code 0x800b0101, here’s a list of potential fixes that other affected users have successfully used to get to the bottom of this issue:
1. Change the Date & Time to correct values
As the message of this error is pointing out, chances are this error is occurring due to a security certificate that fails to be validated by WU because the time or date (or both) is way off from the values expected by the validation server.
There aren’t a lot of conditions that you (as a visitor) need to meet in order to be allowed to download pending Windows Updates, but passing the timestamp check is one of them.
Go ahead and check if your system’s date & time is not off by a manner of days (or months, or years).
If it is, here’s a quick guide on how to ensure that you’re using the correct time and date:
- Press Windows key + R to open up a Run dialog box. Then, type “timedate.cpl” and press Enter to open up the Date and Time panel.
Opening the Time Date window - Once you’re inside the Date and Time window, go over to the Internet Time tab and click on Change settings. When you are prompted by the UAC (User Account Control), click Yes to grant admin access.
Accessing the Date and time menu - Inside the Internet Time settings, check the box associated with Synchronize with an Internet time server, set the Server to time.windows.com, and click on Update now.
Accessing the Internet Settings - Move over to the Date and Time tab, click on Change time zone and make sure you’re using the correct one. Next, click on Change date and time and ensure that the date is selected properly.
Accessing the Correct Date and Time - Restart your computer and see if the issue has been resolved by repeating the action that was previously triggering the 0x800b0101.
If the same error occurs while attempting to use the Windows Update Standalone installer, move down to the next potential fix below.
2. Run the SFC and DISM scans
Since the issue is most likely related to some kind of corruption affecting either Windows Update or Windows Installer, one of the troubleshooting fixes that you should definitely explore is to scan for any corrupted Windows files.
To do this, you’ll need to run a couple of scans with two built-in utilities – System File Checker (SFC) and Deployment Image Servicing and Management(DISM).
Note: These two tools share some similarities, but they are not meant to replace one another. We recommend that you run both scans in quick succession in order to improve your chance of fixing the corrupted system files.
You should start with a simple SFC scan.
Note: This tool is entirely local, so you won’t be required to be actively connected to the Internet.
Important: Once you initiate this procedure, it’s very important to not close the CMD window even if the utility looks like it froze. Wait until the process is complete because interrupting the operation might cause logical errors on your HDD/SSD.
Once the SFC scan is completed successfully, go ahead and reboot your computer and see if the issue is fixed once the next computer startup is complete by attempting to perform the action that was previously triggering the 0x800b0101 error.
I the same error is still popping up when you do this, deploy a DISM scan and follow the on-screen prompts to complete the operation.
Note: Different from SFC, this tool uses a sub-component of Windows Update to download healthy equivalents to replace corrupted system files. Because of this, you need to make sure that you have reliable Internet before initiating this operation.
Once the DISM scan has been completed successfully, restart your computer once again and see if the 0x800b0101 error is now fixed.
In case you’re still dealing with the same issue, move down to the next potential fix below.
3. Use the Windows Update Catalog (if applicable)
If you are seeing this error while trying to install a pending update for System Center Configuration Manager, the error 0x800b0101 is most likely occurring due to the missing of a few critical updates that need to be installed in first – Update KB2756872 and KB2749655.
If this scenario is applicable in your particular case, follow the instructions below to utilize the Microsoft Update Catalog to download and install the required updates first (before installing the System Center Configuration Manager update)
If you’re looking for step by step instructions on how to do this, follow the instructions below:
- Access the official Microsoft Update Catalog page on the affected machine from your favorite browser.
- Next, use the search function (on the right) to search for the KB2756872 update and press Enter to generate the results.
Searching for the missing updates - Once the results appear, identify the version that’s compatible with your Windows build by looking at the OS architecture and the Windows version.
Downloading the Correct version of the update
Note: If you don’t know your OS architecture, right-click on This PC in File Explorer and choose Properties from the context menu. Next, from the list of results, look at the System type and check the bit version of your OS.
- After you decide on the correct update that you need to install on your computer, click on the Download button and wait for the process to complete.
- After the download is complete, navigate to the location where the update was downloaded, right-click on the .inf file and choose Install.
Installing the correct update - Follow the on-screen instructions to complete the installation, then repeat steps 2 to 5 with the remaining update (KB2749655)/
- After every pending update is successfully installed, reboot your machine before finally installing the failing System Center Configuration Manager Windows Update.
If this particular scenario was not applicable to your particular situation, move down to the next potential fix below.
4. Download the latest version of AccountRight (if applicable)
If you are encountering the 0x800b0101 while attempting to update or install AccountRight, it’s almost certain that the problem occurs due to a badly written security certificate that got attached to the application version available for download.
This is due to a mess-up by AccountRight developers that assigned a years old expiration date.
Fortunately, the issue was since fixed, so the problem can be responded to simply by downloading the patched version of AccountRight.
If you find yourself in this particular scenario, follow the instructions below to download & install the correct version of AccountRight:
- Open your default browser and visit this link here to download the patched version of the AccountRight installer.
- Once the download is complete, right-click on it and choose Run as administrator. This is essential since the installation needs admin access in order to complete without errors.
- At the first installation prompt, check the box associated with I accept the license agreement and terms of use, then click on Install and follow the remaining prompts.
Installing the patched version of the AccountRight app - After the installation is complete, reboot your computer and open the app once the next startup is complete, and complete the installation of the remaining updates.
