    • Under "Get up and running," select "Windows Update" and then click "Run the troubleshooter."
    • Follow the on-screen instructions to identify and resolve any issues with Windows Update.
  3. Check for Pending Updates: Make sure there are no other updates that are currently being installed or pending. Sometimes, multiple updates can conflict with each other.

  4. Check for Sufficient Disk Space: Ensure that you have enough free disk space on your system drive (usually the C: drive) for the updates to be installed.

  5. Disable Antivirus and Firewall: Sometimes, security software can interfere with updates. Temporarily disable your antivirus and firewall, then try installing the updates. Remember to re-enable them afterward.

    • Close Command Prompt and try to update again.
  7. Manually Install the Update: If you know which update is causing the issue, you can try downloading the update manually from the Microsoft Update Catalog and then installing it.

  8. Check System Integrity:

    • Open Command Prompt as an administrator.
    • Run the following command: sfc /scannow
    • This will scan and repair system file integrity issues. Reboot your computer afterward.
