How to use Win32_LoggedOnUser WMI classes??

The 2 Properties defined within this class is:

Code:

---

class Win32_LoggedOnUser : CIM_Dependency
{
  Win32_Account ref Antecedent;
  Win32_LogonSession ref Dependent;
};

---

I could not understand how to retrieve information using this class. If anyone could could give some tips??

Thank you

I am just trying to retrive the current logged on user name using this WMI class.
