How To Solve Errors

There are several troubleshooting steps you can take to resolve error code 0xe40200aa:

Run the Windows Update Troubleshooter

Windows includes a built-in troubleshooter designed to address common update issues.

  1. Go to Settings by pressing the Windows key + I.
  2. Select Update & Security.
  3. Click on Troubleshoot in the left sidebar.
  4. Select Windows Update and click Run the troubleshooter. Follow the onscreen instructions.

Check Your Internet Connection

Ensure your internet connection is stable and that you can access other websites without issues. Try restarting your router or modem. If you're using a firewall, temporarily disable it to see if it's interfering with the update process.

Clear the Windows Update Cache

Clearing the Windows Update cache can sometimes resolve corrupted files.

  1. Open Command Prompt as an administrator (right-click on the Start menu and select "Command Prompt (Admin)").

  2. Type the following commands, pressing Enter after each one:

    • net stop wuauserv
    • net stop cryptSvc
    • net stop bits
    • net stop msiserver

  3. Navigate to C:\Windows\SoftwareDistribution and delete all files and folders within this directory.

  4. Restart the following services by typing the commands below:
    • net start wuauserv
    • net start cryptSvc
    • net start bits
    • net start msiserver

Run System File Checker (SFC)

The SFC tool scans your system for corrupted files and attempts to repair them. Open Command Prompt as an administrator and type: sfc /scannow

Press Enter and allow the scan to complete.

Reset Windows Update Components

Resetting the Windows Update components can often resolve persistent issues. Open Command Prompt as an administrator and run the following commands sequentially, pressing Enter after each one:

  • net stop wuauserv
  • net stop cryptSvc
  • net stop bits
  • net stop msiserver

Rename the SoftwareDistribution and Catroot2 folders:

  • ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
  • ren C:\Windows\System32\catroot2 Catroot2.old

Restart the services you stopped earlier: * net start wuauserv * net start cryptSvc * net start bits * net start msiserver

Update Your Drivers

Outdated drivers can sometimes contribute to update problems. Use Device Manager (accessible by right-clicking the Start menu and selecting "Device Manager") to check for driver updates. You can also download the latest drivers from your device manufacturer's website.

Perform a Clean Boot

Performing a clean boot disables nonessential startup programs and services, which can help identify software conflicts that might be causing the error. Instructions for performing a clean boot can be found on Microsoft's website (download the Windows Update troubleshooter from there).

If none of these solutions resolve the issue, it may be necessary to seek further assistance from Microsoft support or consult with a qualified computer technician.
