Hello David McDonald,
General troubleshooting for Windows Update is mentioned here: Troubleshoot problems updating Windows - Microsoft Support
Please go through all the checks listed to help resolve the issue. Additionally, if updates are managed via Group Policy or Intune, ensure that there is no deferral settings configured and that Quality Updates are not paused.
If the issue persists, please share:
• How updates are being deployed (manual, Intune, or GPO)
• Any error codes or messages you’re seeing
You can also test on another device with the same Intune or GPO policy applied to see if the issue is reproducible.
