WU_E_PT_INVALID_CONFIG_PROP means a property used by the update protocol was present but had a value the client could not accept. The relevant property may originate from policy, service configuration, or metadata.
How to investigate
- Find the property name or configuration object in the log lines immediately before this error.
- For managed clients, compare Group Policy and update-service settings with a working device.
- If the issue is server-specific, review the WSUS configuration and recent synchronization or publishing changes.
