Troubleshoot problems updating Windows 10

In Windows 10, you decide when and how to get the latest updates to keep your device running smoothly and securely. This article will help you answer questions and troubleshoot common problems with your Windows 10 update.

If you’re looking for info on how to activate Windows 10 or to verify that your installation of Windows 10 is activated, see Activate Windows 10.

Have issues installing Windows updates? Start here.

Your device may not be able to update to the latest version of Windows 10 for a few reasons. The following tips can help you pinpoint the issue affecting your device.

Before you begin, make sure your device is plugged into a power source and connected to the internet. Then, try the steps listed below to get your PC to update.

Some updates require administrator access. If your account doesn’t have administrator access, see Create a local user or administrator account in Windows 10. Or if someone else at home or in your office has an administrator account on your device, try asking them to install the updates.

Before trying any of the solutions below, make sure you back up your personal files. You can use File History to back up your files to another drive, or insert a USB drive and use File Explorer to drag and copy important files to the USB drive. If you’re signing into Windows with a Microsoft account, your system settings will be automatically restored after updating, once you’re connected to the internet.

You can also back up your files with OneDrive. For more info, go to Back up your Documents, Pictures, and Desktop folders with OneDrive.

Make sure that your device has enough space. Your device requires at least 16 GB of free space to upgrade a 32-bit OS, or 20 GB for a 64-bit OS. If your device has a small hard drive, you may need to insert a USB drive to update it.

If your PC is running low on storage, try the techniques at Free up drive space in Windows 10.

Many updates require you to restart your device. Save your work and close all open applications. Then, select Start > Power , and select either Update and restart or Update and shut down.

Even if you have downloaded some updates, there may be more available. After trying the preceding steps, run Windows Update again by selecting Start > Settings > Update & Security > Windows Update > Check for updates. Download and install any new updates.

Remove any external storage devices and drives, docks, and other hardware plugged into your device that aren’t needed for basic functionality. Then try to run updates again and see if this resolved your issue. If it didn’t, continue to the next tip.

If you’ve added hardware to your device, check for third-party driver updates and installation instructions on the hardware manufacturer’s website. Update any drivers, then try to run updates again and see if this resolved your issue. If it didn’t, continue to the next tip.

In the search box on the taskbar, type device manager, then select Device Manager from the list of results.

In the window that appears, look for any device with a yellow exclamation mark next to it. (You may have to select each category to view the list of devices.) Select the device name.

Select Action, and then choose either Update driver or Uninstall to correct the errors.

Common troubleshooting questions

If you are receiving an error message with a specific error code, try running the Windows Update Troubleshooter. If that doesn’t resolve the issue, see Fix Windows Update errors and follow the instructions to help resolve common update issues.

The time required to download and install updates depends on connection speed, network settings, and the size of the update. If the installation remains stuck at the same percentage, try checking for updates again or running the Windows Update Troubleshooter.

To check for updates, select Start > Settings > Update & Security > Windows Update > Check for updates.

To get help, in the search box on the task bar, type get help, then select Get Help from the list of results. To leave feedback if you run into further problems, in the search box on the taskbar, type feedback hub, then select Feedback Hub from the list of results.

Windows 10 is the most secure Windows ever, and we recommend you stay updated to protect your PC from security risks and to keep it running smoothly. However, you can temporarily pause updates as well as schedule a restart to install updates at a time that’s convenient for you.

Find out how to schedule a restart to install updates at a convenient time

You will only receive a notification when it’s time to restart your computer to apply the installed updates.

If you need to know where you left off in your work after an update, use Timeline to jump back in.

To get started with Timeline, select Task View on the taskbar, or press the Windows logo key +Tab and select the activity you want to resume.

Monthly quality updates on Windows 10 are quite small and have a minimal impact on data usage. Feature updates typically happen twice per year, and you can control when to install them. They require more data but are less frequent.

If you’re on a metered connection, some updates for Windows won’t be installed automatically. Metered connections in Windows 10

Your computer might be slow for a number of reasons, but updating to the latest version of Windows 10 can improve its performance. For help with a slow computer, see Tips to improve PC performance in Windows 10.

If you’re having trouble finding your files after an upgrade, see Find lost files after the upgrade to Windows 10 for other things to try.

Warning: Microsoft only recommends trying the procedures in this section if you’re comfortable working in the command line. These procedures require administrator permissions on your device.

In the search box on the taskbar, type command prompt, then select Run as administrator from the list of options. Select Yes. Next, in the window that appears, type the following commands one at a time, including the spaces as shown. After you type each command, press Enter. Then let each command complete before you type the next command.

net stop wuauserv

ren %systemroot%\softwaredistribution softwaredistribution.bak

ren %systemroot%\system32\catroot2 catroot2.bak

net start wuauserv

After all these commands are completed, close the Command Prompt window and restart your computer.

In some instances, third-party antivirus or security software can cause errors when you try to update to the latest version of Windows 10. You can temporarily uninstall this software, update your PC, and then reinstall the software after your device is up to date. We recommend using third-party antivirus or security software that’s compatible with the latest version of Windows 10. You can check compatibility by visiting the software manufacturer’s website.

Note: Before uninstalling software, make sure you know how to reinstall your programs and that you have any necessary product keys.

In the search box on the taskbar, type command prompt, and then select Run as administrator from the list of options. Select Yes. In the window that appears, type the following command, including the space as shown:
chkdsk/f C:
and then press Enter. Repairs will automatically start on your hard drive, and you’ll be asked to restart your device.

A clean restart starts Windows with a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program or an update that may cause issues updating your PC.
Learn how to do a clean restart

In the search box on the taskbar, type command prompt, then select Run as administrator from the list of options.

In the window that appears, type this command including spaces as shown:
DISM.exe /Online /Cleanup-image /Restorehealth

Press Enter. When the command operation has run successfully, you’ll see a confirmation message from Command Prompt that says, “The restore operation completed successfully” or “The operation completed successfully”.
Note: If you don’t see a confirmation message, retype the command and try again.

Next, type this command, including the space as shown:
sfc /scannow

Press Enter. Wait until the sfc scan verification reaches 100% completion, and then close Command Prompt.

Try running the Windows Update again.

Go to the software download page and select Download tool now to download the clean installation tool. Make sure to carefully read the notes on the software download page before using the tool.

Обновления для Windows 10 версии 1903 и Windows Server версии 1903

Windows 10 — это служба, качество которой улучшается с каждым обновлением.

Обычно вам не нужно ничего делать, чтобы получить обновления. Если вы включили автоматические обновления, новые обновления будут автоматически скачиваться и устанавливаться, когда они будут становиться доступны, поэтому не стоит беспокоиться об этом.

В левой части страницы находится список всех обновлений, выпущенных для данной версии Windows. Вы также можете найти дополнительные сведения о выпусках и любых известных проблемах. Последнее обновление включает в себя все предыдущие обновления, которые вы могли пропустить, в том числе важные обновления для системы безопасности.

Последнюю информацию об известных проблемах с Windows и Windows Server можно найти на информационной панели работоспособности выпуска Windows.

Примечания и сообщения

Общие

ВНИМАНИЕ! Заметки о выпуске изменяются! Сведения о новом URL-адресе, обновлении метаданных и другая информация содержится в разделе Планируемые изменения заметок о выпуске Windows.

ВАЖНО! С июля 2020 г. мы возобновим выпуск не связанных с безопасностью обновлений для Windows 10 и Windows Server версии 1809 и более поздних. В накопительные ежемесячные обновления для системы безопасности (также называемые выпусками «B» или выпусками обновлений по вторникам) изменения не вносятся. Дополнительные сведения см. в записи блога Возобновление необязательных ежемесячных обновлений, не связанных с безопасностью, для Windows 10 и Windows Server.

ВАЖНО! С июля 2020 г. во всех Центрах обновления Windows отключается функция RemoteFX vGPU из-за уязвимости в системе безопасности. Дополнительные сведения об этой уязвимости см. в CVE-2020-1036 и KB4570006. После установки этого обновления попытки запуска виртуальных машин (ВМ), в которых включена функция RemoteFX vGPU, будут завершаться сбоем и будут появляться следующие сообщения:

Если повторно включить функцию RemoteFX vGPU, появится следующее сообщение:

«Виртуальная машина не может быть запущена, так как все GPU с поддержкой RemoteFX отключены в диспетчере Hyper-V».

«Не удается запустить виртуальную машину, так как на сервере недостаточно ресурсов GPU».

«Видеоадаптер RemoteFX 3D больше не поддерживается. Если вы все еще используете этот адаптер, ваша безопасность под угрозой. Подробнее (https://go.microsoft.com/fwlink/?linkid=2131976)”

Новые возможности Windows 10 версии 1909 и заметки о выпуске Windows 10 версии 1903

Windows 10 версии 1903 и 1909 совместно используют общую базовую операционную систему и один и тот же набор системных файлов. В результате новые возможности Windows 10 версии 1909 были включены в последнее ежемесячное обновление для Windows 10 версии 1903 (выпущено 8 октября 2019 г.), но в данный момент они находятся в неактивном состоянии. Они останутся неактивными до тех пор, пока не будут включены с помощью пакета Enablement — небольшого и быстро устанавливаемого обновления, которое просто активирует возможности Windows 10 версии 1909.

В соответствии с этим изменением заметки о выпуске для Windows 10 версии 1903 и версии 1909 будут использовать общую страницу журнала обновлений. Каждая страница выпуска содержит список устраненных проблем для версий 1903 и 1909. Обратите внимание, что версия 1909 всегда будет содержать исправления для версии 1903, однако версия 1903 не будет содержать исправлений для версии 1909. На этой странице вы найдете номера сборок для версий 1909 и 1903, что упростит обращение в службу поддержки при возникновении проблем.

Дополнительные сведения о пакете Enablement и о том, как получить обновление компонентов, см. в блоге Параметры доставки Windows 10 версии 1909.

Окончание обслуживания

ВАЖНО! 8 декабря 2020 г. будет прекращено обслуживание Windows 10 версии 1903. Для получения обновлений системы безопасности и исправлений корпорация Майкрософт рекомендует обновить Windows 10 до последней версии. Если вы хотите обновить систему до Windows 10, версии 1909, нужно использовать пакет включения KB4517245(EKB). Использование EKB ускоряет и упрощает обновление и требует однократной перезагрузки. Дополнительные сведения см. в разделе Варианты доставки Windows 10 версии 1909.

Notes and messages

General

IMPORTANT Release notes are changing! To learn about the new URL, metadata updates, and more, see What’s next for Windows release notes.

IMPORTANT Starting in July 2020, we will resume non-security releases for Windows 10 and Windows Server, version 1809 and later. There is no change to the cumulative monthly security updates (also referred to as the «B» release or Update Tuesday release). For more information, see the blog post Resuming optional Windows 10 and Windows Server non-security monthly updates.

IMPORTANT Starting in July 2020, all Windows Updates will disable the RemoteFX vGPU feature because of a security vulnerability. For more information about the vulnerability, seeCVE-2020-1036 and KB4570006. After you install this update, attempts to start virtual machines (VM) that have RemoteFX vGPU enabled will fail, and messages such as the following will appear:

If you re-enable RemoteFX vGPU, a message similar to the following will appear:

“The virtual machine cannot be started because all the RemoteFX-capable GPUs are disabled in Hyper-V Manager.”

“The virtual machine cannot be started because the server has insufficient GPU resources.”

«We no longer support the RemoteFX 3D video adapter. If you are still using this adapter, you may become vulnerable to security risk. Learn more (https://go.microsoft.com/fwlink/?linkid=2131976)”

What’s new for Windows 10, version 1909 and Windows 10, version 1903 release notes

Windows 10, versions 1903 and 1909 share a common core operating system and an identical set of system files. As a result, the new features in Windows 10, version 1909 were included in the recent monthly quality update for Windows 10, version 1903 (released October 8, 2019), but are currently in a dormant state. These new features will remain dormant until they are turned on using an enablement package, which is a small, quick-to-install “master switch” that simply activates the Windows 10, version 1909 features.

To reflect this change, the release notes for Windows 10, version 1903 and Windows 10, version 1909 will share an update history page. Each release page will contain a list of addressed issues for both 1903 and 1909 versions. Note that the 1909 version will always contain the fixes for 1903; however, 1903 will not contain the fixes for 1909. This page will provide you with the build numbers for both 1909 and 1903 versions so that it will be easier for support to assist you if you encounter issues.

For more details about the enablement package and how to get the feature update, see the Windows 10, version 1909 delivery options blog.

End of servicing

IMPORTANT Windows 10, version 1903 will reach end of servicing on December 8, 2020. To continue receiving security and quality updates, Microsoft recommends that you update to the latest version of Windows 10. If you want to update to Windows 10, version 1909, you must use the Enablement Package KB4517245(EKB). Using the EKB makes updating faster and easier and requires a single restart. For more information, see Windows 10, version 1909 delivery options.
