>>> wm.Win32_ComputerSystem.UnjoinDomainOrWorkgroup
<function UnjoinDomainOrWorkgroup (FUnjoinOptions, Password, UserName) =>
(ReturnValue)>

The parameter sequence says FUnjoinOption, Password and Username while MOF
says

uint32 UnjoinDomainOrWorkgroup(
  [in]  string Password,
  [in]  string UserName,
  [in]  uint32 FUnjoinOptions = 0
);

This is confusion for this reason.

Thanks.
