WU_E_UH_UNKNOWNHANDLER

WU_E_UH_UNKNOWNHANDLER means the update references a handler that the local Windows Update Agent cannot recognize. The update metadata, the local servicing stack, or the expected plugin set may not match.

What to verify

Confirm that the device is fully supported for the update being offered.
Look in WindowsUpdate.log for the handler name and update identity that triggered the failure.
If this comes from managed update content, verify that the metadata source is intact and not stale or partially synchronized.
