How to fix "Windows Update Agent Installer Encountered Unrecoverable Error"

Use a special repair tool

You can always use a dedicated software tool that quickly scans your computer to update, repair, and fix corrupt or outdated drivers or applications.

  1. We recommend a third-party tool that effectively detects and updates outdated drivers. Speed scanning is simply necessary to capture the condition of your driver in the blink of an eye.
  2. Once the scan is complete, you will be informed of the damaged areas of your computer and what you can do about them.
  3. This third-party tool also has automatic driver updates that you can enable to get the latest updates in real-time.

Launch Windows Troubleshooter

  1. Open Settings -> Update and Security.
  2. Click Troubleshooting -> go to Windows Update.
  3. Click on “Run Troubleshooter.”

This is the easiest way for Windows to detect problems and fix them. If the problem is not complex (such as missing or corrupt registry files), the system will find resources to fix the problem without further intervention.

If not, the process will also let you know if additional steps are needed.

Run the System File Checker

  1. In the search bar, type cmd on your keyboard.
  2. Run it as administrator.
  3. In the command line window, type sfc / scan now and press Enter.

This process, which may take a few minutes, should identify and fix any problems with registry files or system links.

Likely, running this command won’t fix the Windows Update Installer error, but at least the log files will show you what the problem is. Then you can move on to another solution.

Run the DISM image recovery tool

  1. Open the command prompt as in the previous step and run it as an administrator.
  2. Enter the following commands one by one:
  3. DISM /Online /Cleanup-Image /CheckHealth
  4. DISM /Online /Cleanup-Image /ScanHealth
  5. DISM /Online /Cleanup-Image /CheckHealth

The system should restore the corrupted files that it found again. However, many users have reported that they were able to run this process, it fixed some files, but the Windows Update Installer Agent error was never fixed.

Install a clean Windows image

  1. Collect the installation CD, product key, and everything else you need to reinstall the operating system.
  2. Type Windows Security in the search box -> Open.
  3. Navigate to Performance and Health.
  4. Scroll down to Restart -> More information.
  5. Click Restart and follow the procedure. Restart the device after the process is complete.
