If Windows updates won’t download or keep failing, there could be various reasons behind this issue. One of the most common reasons for update failures is insufficient disk space. Ensure that your device has enough free space to accommodate the updates.

Unstable or slow internet connections can cause problems during the download or installation of updates. Make sure your internet connection is stable.

Corruption in the Windows Update components can lead to update failures. Antivirus or security software can interfere with the update process. Temporarily disable or configure your security software to allow Windows updates.

Sometimes Windows updates may fail or the system can’t apply the latest updates due to the interference of third-party antivirus software. Let’s temporarily disable your antivirus and disconnect from VPN (if configured on your system) and check if the problem persists.

You can use a speed test tool to measure your download and upload speeds. If your connection is slow or unstable, try restarting your router or modem, or switching to a wired connection instead of Wi-Fi.

Also, you should restart your PC/Windows 10 and check for Windows updates again, that probably fixes the problem if a temporary glitch causes the issue.

Free up some disk space

The update may fail if you don’t have enough free space on your system drive. To free up some space, you can use the Disk Cleanup tool to delete unnecessary files, such as temporary files, recycle bin items, or old system restore points. You can also uninstall any programs or apps that you don’t use anymore.

  • To access the Disk Cleanup tool, go to Start > Settings > System > Storage > Temporary files. Select the files you want to delete and click Remove files.
  • To uninstall programs or apps, go to Start > Settings > Apps > Apps & features. Select the program or app you want to uninstall and click Uninstall.
