  5. Run System File Checker (SFC) and DISM

    Corrupted system files can cause update errors. Use SFC and DISM to repair these files.

    1. Open Command Prompt as an administrator.
    2. Type the following command and press Enter:
      sfc /scannow
    3. After the SFC scan completes, run the DISM tool:

    2. Search for the update using its KB number.
    3. Download and install the update manually.
  10. Perform a Clean Boot

    Performing a clean boot can help you determine if a background program is causing the issue.
