• Stop the Windows Update service by executing this command:
  
  Code:

• Next, you'll need to delete specific data:
  • Delete the SoftwareDistribution and catroot2 folders, which store Windows Update files.
    • Navigate to the following paths and delete the corresponding folders:
      • C:\Windows\SoftwareDistribution
      • C:\Windows\System32\catroot2
• Once you've deleted these folders, restart the Windows Update service:

4. Download the Update Manually
If automatic updates fail, consider downloading the necessary update directly:

• Visit the Microsoft Update Catalog.
• Use the search bar to find the specific update you are trying to install (like cumulative updates).
• Download the appropriate version for your architecture (32-bit or 64-bit) and install it manually.

Additional Considerations​

• Antivirus Interference: Sometimes, antivirus software can block critical updates. If you suspect this may be the case, try temporarily disabling your antivirus software before running the updates.
• Corrupted Update Packages: If a specific update package is corrupted, it could prevent installations. In such instances, consider clearing your Windows Update history or performing a System File Check (SFC) using the command:
  
  Code:

  bash sfc /scannow
