WU_E_INVENTORY_PARSEFAILED

WU_E_INVENTORY_PARSEFAILED means the Windows Update inventory component could not parse a rule file used to collect device information for update applicability. The failure is in the rule or its delivered data, not in downloading the update payload.

What to check

  • Generate WindowsUpdate.log and identify the rule name, update service, and parser error immediately before this HRESULT.
  • Determine whether the error is limited to one managed update source or affects all scans on the device.
  • For an internally managed catalog, verify the integrity of the inventory metadata rather than editing local rule files by hand.
