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.

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.

What to Know

• Checking for and installing Windows updates, like service packs or patches, is a necessary for running any Windows operating system.
• The updates can solve specific problems with Windows, provide protection from malicious attacks, or even add new features.

This article includes instructions for installing updates for Windows 10 and other editions all the way back to Windows 98.

How to Check for and Install Windows Updates

Windows updates are most easily installed using the Windows Update service. While you could certainly download updates manually from Microsoft’s servers, updating via Windows Update is considerably easier to do.

The Windows Update service has changed over the years as Microsoft released new versions of Windows. While Windows updates used to be installed by visiting the Windows Update website, newer versions of Windows include a special built-in Windows Update feature with more options.

Below is the best way to check for, and install, Windows updates based on your version of Windows. You’ll need to know which version of Windows you have to make sure you’re following the correct steps for your computer.

Check for and Install Updates in Windows 10

In Windows 10, Windows Update is found within Settings.

To get there, select the Start menu, followed by the gear/settings icon to the left. In there, choose Update & Security and then Windows Update on the left.

Check for new Windows 10 updates by choosing Check for updates.

In Windows 10, downloading and installing updates is automatic and will happen immediately after checking or, with some updates, at a time when you’re not using your computer.

Check for and Install Updates in Windows 8, 7, and Vista

In Windows 8, Windows 7, and Windows Vista, the best way to access Windows Update is via the Control Panel.

In these versions of Windows, Windows Update is included as an applet in Control Panel, complete with configuration options, update history, and lots more.

Just open Control Panel and then choose Windows Update.

Select Check for updates to check for new, uninstalled updates. Installation sometimes happens automatically or it might need to be done by you via the Install updates button, depending on what version of Windows you’re using and how you have Windows Update configured.

Microsoft no longer supports Windows 7, and as such, doesn’t release new updates. Any updates available via Windows 7’s Windows Update utility are ones that have not been installed since support ended on January 24, 2020.

Microsoft no longer supports Windows Vista, and as such, doesn’t release new updates. Any updates available via Windows Vista’s Windows Update utility are ones that have not been installed since support ended on April 11, 2017.

Check for and Install Updates in Windows XP, 2000, ME, and 98

In Windows XP and previous versions of Windows, Windows Update is available as a service hosted on Microsoft’s Windows Update website.

Similar to the Control Panel applet and Windows Update tool in newer versions of Windows, available Windows updates are listed, alongside a few simple configuration options.

Checking for, and installing, uninstalled updates is as easy as selecting those respective links and buttons on the Windows Update website.

Microsoft no longer supports Windows XP, nor versions of Windows that preceded it. While there might be Windows updates available for your Windows XP computer on the Windows Update website, any you see will be updates released prior to the end of support date for Windows XP, which was on April 8, 2014.

More on Installing Windows Updates

The Windows Update service isn’t the only way to install Windows updates. As mentioned above, updates to Windows can also be downloaded individually from Microsoft Download Center and then installed manually.

Another option is to use a free software updater program. Those tools are usually built specifically for updating non-Microsoft programs but some include a feature for downloading Windows updates.

Most of the time, Windows updates are installed automatically on Patch Tuesday, but only if Windows is configured that way. See How to Change Windows Update Settings for more on this and how to change how updates are downloaded and installed.
