WU_E_DS_INVALID
WU_E_DS_INVALID indicates a state mismatch in the Windows Update data store. The agent expected the store to be in one state, but found another, which can happen after an interrupted update transaction or inconsistent cached metadata.
Recommended investigation
- Generate
WindowsUpdate.logand identify the first data-store error in the sequence. - Check for interrupted reboots, service crashes, power loss, or manual component-reset actions shortly before the failure.
- When multiple update operations fail with store-state errors, preserve logs and use a supported recovery workflow rather than deleting system folders while the service is active.
