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.

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.
