WU_E_MISSING_HANDLER

WU_E_MISSING_HANDLER means a local component needed for applicability detection is missing. Until that component is available, scans may fail before any download is attempted.

What to check

Verify that the Windows installation is supported and that its servicing components have not been removed or damaged.
Review the Windows Update log for the missing handler name and the update category that triggered it.
Use supported Windows repair and servicing procedures instead of copying DLLs or plugins from another machine.
