If you want to know how to fix Windows update error or install, a good first step is to reboot your machine and ping your internet connection. Then, you can run the Windows Update Troubleshooter through Settings > Update & Security > Troubleshoot. You can clean the Windows Update cache by halting the Windows Update service, removing files from the SoftwareDistribution folder, and then reactivating the service. Additionally, verify that there is sufficient disk space and turn off the antivirus software temporarily. To top it off, you may opt to run the DISM and SFC command-line instructions to fix system file corruption. And if all else fails, fetching the update from the Microsoft Update Catalog and installing it manually is a viable option.
