   - The registry settings of COM/DCOM has been damage or wrongly modified.
   - The registry security settings of COM/DCOM has been damage or wrongly modified.

   the following DCOM objects:
   - 'My Computer'
   - 'Windows Management Instrumentation'
   - 'Microsoft WMI Provider Subsystem Host'
   - 'Microsoft WBEM UnSecured Apartment'

    - a WMI repository corruption.
      In such a case, you must rerun WMIDiag with 'WriteInRepository' parameter
      to validate the WMI repository operations.
    Note: ENSURE you are an administrator with FULL access to WMI EVERY namespaces of the computer before
          executing the WriteInRepository command. To write temporary data from the Root namespace, use:
          i.e. 'WMIDiag WriteInRepository=Root'
    - If the WriteInRepository command fails, while being an Administrator with ALL accesses to ALL namespaces
      the WMI repository must be reconstructed.
    Note: The WMI repository reconstruction requires to locate all MOF files needed to rebuild the repository,
          otherwise some applications may fail after the reconstruction.
          This can be achieved with the following command:
          i.e. 'WMIDiag ShowMOFErrors'
    Note: The repository reconstruction must be a LAST RESORT solution and ONLY after executing
          ALL fixes previously mentioned.
!! WARNING: Static information stored by external applications in the repository will be LOST! (i.e. SMS Inventory)
