To continue receiving security and quality updates, and to ensure that your device is protected from security risks and viruses, Microsoft recommends updating to the latest version of Windows 10. If you’re currently running an older version of Windows 10, you may receive a notification that your device needs the latest security updates, and it will then attempt to update Windows. If the update fails with an error message, "Something went wrong", you may need to attempt the troubleshooting steps in this article to successfully update your device.
There are many possible reasons your device may be unable to update to the latest version of Windows. Here are a few steps you can try:
Important: Before attempting any of the solutions below, it’s a good idea to back up your personal files. Some steps might require resetting the PC or might uncover a more serious issue and protecting your data is important. 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 are signing into Windows with a Microsoft account, any personalized settings you have will be automatically restored once you’re connected online.
- Make sure your device has enough disk space to install updates. Your device requires at least 16 GB of free space to upgrade a 32-bit version of Windows, or 20 GB for a 64-bit version. For more info, see Free up drive space in Windows 10.
- Run Windows Update a few times to download and install any available updates. There may be software updates, security updates, and driver updates available that are required before you can run the latest version of Windows. Use the Windows Update Troubleshooter to try fixing any Windows Update errors you may receive, or you can try the steps recommended at Fix Windows Update errors for the specific error you are receiving.
- Check your hardware manufacturer’s support site for updated drivers and download any updates that are available.
- Disconnect any extra hardware you have attached to your device. Remove all external storage devices and drives, docking stations, or other hardware you might have plugged into your device that isn’t needed for basic functionality.
- Check the Device Manager for errors. In the search box on the taskbar, type Device Manager and select it from the results. Within Device Manager, look for any device with a yellow exclamation mark beside it. (You may have to expand each category to see the full list of devices.) If any devices are showing an error, press and hold (or right-click) the device name and select either Update Driver Software, or Uninstall.
- Temporarily uninstall any third-party security software that may be running. Make sure you know how to reinstall your programs and that you have any product keys that may be necessary to reinstall your security software after the update is completed. Windows Defender will help protect your device in the meantime.
- Try performing a clean boot of Windows and then retry the update.
- Check your hard drive for errors. In the search box on the taskbar, type Command Prompt. Right-click Command Prompt in the search results and select Run as administrator. In the Command Prompt window that opens, type the following command and press the Enter key:
Repairs will start automatically if any errors are found, and you’ll be asked to restart your device.
- Try restoring and repairing your system files. In the search box on the taskbar, type Command Prompt. Right-click Command Prompt in the search results and select Run as administrator. In the Command Prompt window that opens, type the following command and press the Enter key:
DISM.exe /Online /Cleanup-image /Restorehealth
Installing the latest version of Windows might require you to update the BIOS or firmware of your PC. To do this, go to your PC manufacturer’s support website, and search using the serial number or model of your PC to locate any BIOS or firmware updates that may be available. Follow the instructions on the manufacturer's website for doing this process safely. Once the BIOS update is completed, retry updating Windows.
Download, install, and run the Malicious Software Removal Tool (MSRT) to check for and remove any malware that may be preventing a successful update.
Try a fresh start by performing a clean install of Windows.
What happens if I continue to use a version of Windows 10 that is no longer supported?
If you continue to use a version that is no longer supported, your computer will still work, but since you won’t continue to receive new security updates or other quality updates, it could become more vulnerable to security risks and viruses. You will also continue to receive notifications to update to the latest version of Windows.
Microsoft offers complimentary support to ensure your device has the latest updates installed and requires that your device be up to date before assisting with other technical support issues.
Why is Microsoft ending service for some older versions of Windows 10, such as version 1507?
With Windows 10, we introduced a new model whereby we release feature updates a few times a year, rather than holding back features for a new release every 2-3 years as in the past. In doing so, it's important that our customers stay current by installing feature updates as they are released.
