WU_E_UH_BADCBSPACKAGEID
WU_E_UH_BADCBSPACKAGEID means the update metadata points to an invalid Component-Based Servicing package identifier, so the handler cannot map the update to the expected CBS package.
Why this matters
- The failure is specific to package identity and metadata, not to proxy or transport.
- Confirm that the content source is healthy and that the client has current servicing components.
- Review the failing package identity in the logs to determine whether one update or an entire metadata source is affected.
