How to Use Windows Update Repair Tool for Windows 10/11

Windows Update is the Microsoft service that allows you to download and install system updates. Although it is perfectly integrated into Windows, it can sometimes fail and an attempt to update the system results in a cryptic error message with a number starting with 0x800. Confusing, but less serious than it seems.

Windows Update errors fall into two categories: download errors and installation errors. In the first case, the download does not start or remains blocked. In the second case, it is the installation that crashes. Fortunately, Windows 10 includes a tool for detecting and correcting Windows Update errors as standard. A simple and practical tool that solves most problems.

How to Use the Windows Update Repair Tool for Windows 10?

The Windows Update diagnostic tool is not located in the section of the same name, and this is probably the main criticism of Microsoft. However, the tool is easily accessible and very simple to use.

  • To access Windows Update, open the Start menu and click on the Settings section.
  • In theWindows Settings window, open the Updateand Security section. TheWindows Update section should appear automatically.
  • When an update error occurs, the Windows Update page displays a message of the type Error encountered, followed by a description of the incident.
  • Select the Troubleshooting section in the left-hand menu.
  • In the right window, scroll down to the Being operational section and click on Windows Update
  • Then click on the Run Troubleshooting Utility button.
  • A window showing the progress of the detection process will appear. Please wait for the analysis to be completed.
  • Once the detection is complete, one or more solutions can be proposed. The solutions are presented in steps. At each step, click on Apply this fix or Apply this fix. You can also choose to ignore the fix if it does not seem relevant, but this is not recommended.
  • It is also possible that a hardware resolution is suggested (connecting an Ethernet cable, for example). In this case, follow the instructions on the screen and then click on Check if the problem is solved.
  • When the steps are complete, the window will display a list of the problems found and the corrections applied or not. Click the Close Troubleshooting Utility button.
  • Restart Windows to complete the operation. You can then try to restart the blocked update in the Windows Update section.

How to Repair and Restore Windows 10 System files?

If the troubleshooting utility didn’t work, it’s possible that the source comes from damage in Windows system files. In this case, you can try to repair them via a simple command line.

  • Open theStart Menu. UnderWindows System, right-clickCommand Prompt, selectMore from the context menu, and thenRun as Administrator.
  • The command prompt window will appear. After the blinking cursor, type the following command: DISM.exe /Online /Cleanup-image /Restorehealth and press Enter to confirm.

Once the operation is finished, close the command prompt window and restart Windows. After the restart, open Windows Update again to check if the update can be performed.

Again, you need to go to Windows Update after the restart to restart the update process.
