Check Firewall and Antivirus Settings

Temporarily disable your firewall and antivirus software to see if they're interfering with Windows Update. If the error disappears, you may need to create exceptions for the Windows Update service in your security software settings.

Verify Internet Connection

Ensure that you have a stable internet connection. Run a speed test or ping Microsoft's servers (e.g., ping www.microsoft.com) to check connectivity.

Use the System File Checker

The System File Checker (SFC) tool scans for and repairs corrupted system files.

  1. Open Command Prompt as administrator.
  2. Type sfc /scannow and press Enter.
  3. Allow the scan to complete, which may take some time.

Manually Download Updates

If the above steps don't resolve the error, you can try downloading updates manually from the Microsoft Update Catalog (https://www.catalog.update.microsoft.com).

  1. Identify the specific update(s) needed for your system.
  2. Download and install them manually.

Perform a System Restore

As a last resort, consider performing a System Restore to revert your computer to a previous state when Windows Update was functioning properly. Remember that this will undo any changes made after the restore point was created.

Remember to back up your important data before attempting a system restore.
