WU_E_AU_NOSERVICE
WU_E_AU_NOSERVICE indicates that the Automatic Updates component could not accept or service an incoming request at that moment. The component may be stopping, unavailable, or blocked by a higher-level configuration problem.
What to check
- Inspect the update log for earlier service-state, policy, or agent initialization errors.
- Check whether the request raced with startup, shutdown, reboot, or an in-progress update operation.
- In a managed environment, verify the configured update service and policy before changing individual client settings.
