From MSDN

//Assumes that pObj is defined as a pointer
// to an IWbemClassObject object.

VARIANT v;
BSTR strClassProp = SysAllocString(L"__CLASS");
HRESULT hr;
hr = pObj->Get(strClassProp, 0, &v, 0, 0);
SysFreeString(strClassProp);

// check the HRESULT to see if the action succeeded.

if (SUCCEEDED(hr) && (V_VT(&v) == VT_BSTR))
{
wprintf(L"The class name is %s\n.", V_BSTR(&v));
}
else
{
wprintf(L"Error in getting specified object\n");
}
VariantClear(&v);
