WU_E_DS_INVALIDTABLENAME
WU_E_DS_INVALIDTABLENAME means a Windows Update component attempted to open an internal table that is not present in the data store.
Why this matters
- The failure is about the local update-store schema, not an HTTP or proxy problem.
- Check for earlier schema, version, or store-initialization errors in
WindowsUpdate.log. - If the condition survives a restart and affects normal scans, investigate a data-store recovery path with logs preserved first.
Separate schema failure from missing update content
The WU_E_DS_* range describes the Windows Update data store, while missing downloaded payloads and transport failures have their own error ranges. An invalid table name therefore points toward the store schema or the component issuing the store request. Proxy changes, DNS tests, or repeated download attempts do not repair an internal table lookup.
Preserve the Windows Update ETW trace before any store reset. In the merged WindowsUpdate.log, look earlier than the final HRESULT for store initialization, version, or table errors and note the client version that opened the store. That sequence can distinguish a one-time recovery condition from a persistent schema mismatch affecting every scan.
