Solution

Windows Update is a set of built-in components which can check and install updates to your operating system, ensuring it stays up to date. The updates can be security, critical, non-critical, recommended and/or feature updates/upgrades.

• Ensure your computer has enough free disk space (for regular security or non-feature updates, ensure at least 1 GB free disk space
• For feature upgrades - ensure a couple of free GBs available
• If using a 3rd party security products (Norton, McAfee, Trend Micro, Avast, etc.) - temporary disable or uninstall them  (antivirus/firewalls/encryption software etc...)
  
  
  
• Troubleshoot Windows Update itself

  Try running these:
