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.

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

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.

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:

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.

Windows Update helps keep your computer up-to-date and secure by downloading and installing the latest security and other updates from Microsoft. Windows Update determines which updates apply to your computer.

Microsoft periodically makes software updates available to users of Windows and other Microsoft software. These include updates that improve reliability and performance, updates that provide new protections against malware and other potentially unwanted software, and upgrades to Windows features. To improve the performance or the reliability of hardware components on the computer, Microsoft may also provide updates to device drivers that are supplied by the computer manufacturer.

If you turn on Windows Update, software components that are directly related to Windows Update will have to be updated occasionally on your computer. These updates must be performed before Windows Update can check for required updates or before it can install other updates. These required updates fix errors, provide ongoing improvements, and maintain compatibility with the Microsoft servers that support Windows Update. If you disable Windows Update, you will not receive these updates.

Windows Update is configured to install updates automatically when you select the recommended option during Windows Out Of Box Experience (OOBE) Setup. You can also turn on Windows Update by selecting one of following settings in the Automatic Updates item in Control Panel:

• Automatic (recommended).
• Download updates for me, but let me choose when to install them.
• Notify me, but don’t automatically download or install them.

After you turn on Windows Update, the required updates to components of Windows Update will be downloaded and installed automatically without notifying you. This behavior occurs regardless of which setting you use to turn on Windows Update. If you do not want to receive required updates, you can disable automatic updates in Control Panel.

The updates to Windows Update itself typically do the following: Address feedback from customers, improve compatibility, service performance and reliability, and enable new service capabilities. When the Windows Update server is updated, a corresponding client update is typically required. During an agent self-update operation, Windows Update Agent files may be added, modified, or replaced. For example, Windows Update Agent files that help display the user experience or that determine whether updates apply to a particular system may be added. This behavior occurs when a system is set to automatically check for available updates. This does not occur when automatic updates are turned off. For example, this behavior does not occur if you select Never check for updates in Windows Vista and Windows 7 or if you select Turn off Automatic Updates in Windows XP.

Administrators will receive the latest version of the Windows Update Agent for deployment through Windows Server Update Services (WSUS).
