When encountering a “Windows Update Failed” error, it means that Windows was unable to install the latest updates. This error can occur due to various reasons, such as network connectivity issues, insufficient disk space, or conflicts with installed software. First, check your internet connection and ensure you have enough free space on your hard drive. Try running the Windows Update Troubleshooter or manually downloading and installing the updates. If the problem persists, seek additional guidance from Microsoft support or community forums.
