WU_E_PT_WMI_ERROR

WU_E_PT_WMI_ERROR means the protocol operation encountered a WMI failure. The HRESULT is broad, so the related WMI event, provider, or earlier error is needed to identify the affected dependency.

What to check

Locate the corresponding WMI and Windows Update events by timestamp.
Check whether the issue affects all update operations or only inventory or management-related actions.
Investigate the first WMI-specific error rather than rebuilding the WMI repository solely from this wrapper code.
