WU_E_NO_UI_SUPPORT
WU_E_NO_UI_SUPPORT means the caller requested a Windows Update user-interface capability that is not available in the current environment. The underlying update engine may still work through supported non-UI APIs.
What to check
- Do not use a UI-dependent operation in a service, remote session, Server Core environment, or other non-interactive context.
- Separate user-interface code from scanning, download, and installation logic.
- Use WUA session and search APIs for unattended inventory and deployment tasks.
