How do I fix the 0xe0000003 Windows update error?

Error 0xe0000003 during Windows Update can be caused by various factors, including corrupted system files, issues with Windows Update components, or conflicts with third-party software. Here are some troubleshooting steps to help you fix the Windows Update error 0xe0000003:

  1. Restart your computer: A simple restart can sometimes resolve temporary glitches with the Windows Update service.

  2. Check your internet connection: Ensure that your device has a stable internet connection. A poor or intermittent connection can interfere with the update process.

  3. Run Windows Update Troubleshooter: Windows includes a built-in troubleshooter that can automatically detect and fix common Windows Update issues. Here's how to use it:

    • Open the Windows Settings (press Windows key + I).
    • Go to "Update & Security" > "Troubleshoot."
    • Under "Get up and running," select "Windows Update."
    • Click on "Run the troubleshooter" and follow the on-screen instructions.
  4. Clear Windows Update cache: Sometimes, corrupted Windows Update cache can cause issues. To clear the cache, follow these steps:

    • Open Command Prompt as an administrator. Right-click on the Start button and select "Windows Terminal (Admin)" or "Command Prompt (Admin)."
    • Type the following commands one by one and press Enter after each:
      net stop wuauserv net stop cryptSvc net stop bits net stop msiserver ren C:\Windows\SoftwareDistribution SoftwareDistribution.old ren C:\Windows\System32\catroot2 catroot2.old net start wuauserv net start cryptSvc net start bits net start msiserver
    • Restart your computer and try updating again.
  5. Reset Windows Update components: If clearing the cache didn't work, you can try resetting the Windows Update components. Microsoft provides a script that can do this automatically. Follow these steps:

    • Download the Windows Update Troubleshooter script from the Microsoft website:
    • Right-click on the downloaded file and select "Run as administrator."
    • Follow the on-screen instructions to reset the Windows Update components.
    • Restart your computer and try updating again.
  6. Check for system file corruption: Run the System File Checker (SFC) and Deployment Image Service and Management Tool (DISM) to check for and repair any corrupted system files. Here's how to do it:

    • Open Command Prompt as an administrator.
    • For SFC, type: sfc /scannow and press Enter.
    • For DISM, type: DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
    • Wait for the process to complete, then restart your computer.
  7. Disable third-party antivirus and security software: Sometimes, third-party antivirus or security software can interfere with Windows Update. Temporarily disable any third-party antivirus or security programs, then try updating again. If the update succeeds, consider updating or reinstalling your security software.

  8. Perform a clean boot: Perform a clean boot to start Windows with a minimal set of drivers and startup programs, which can help identify if any third-party software is causing the issue. Instructions for performing a clean boot can be found on the Microsoft support website.

  9. Check disk for errors: Run the Check Disk utility to scan and fix any disk errors that may be affecting the update process. Open Command Prompt as an administrator and type: chkdsk C: /f (replace "C:" with the appropriate drive letter if your system drive is different).
