Comment (by Kai K.):

 Okay I had a deeper look at my problem.
 {{{
 inline bool get_wmi_class_attribute( std::wstring& strValue, const wchar_t
 *wmi_class, const wchar_t *wmi_class_var)
 {
   ...
   while( 0 == pEnumObject->Next( WBEM_INFINITE_IG, uCount, &pClassObject,
 &uReturned ) )
   {
     com_releaser<IWbemClassObject_IG>
 IWbemClassObject_releaser(pClassObject);
     if ( 0 == pClassObject->Get( L"LastBootUpTime", 0, &vwchar, 0, 0 ) ){
       bRet = true;
       strValue = vwchar.value.pbstrVal;
       VariantClear(&vwchar );
       break;
     }
   }
 }
 }}}
 The call of pEnumObject->Next(...) fails with WBEM_E_ACCESS_DENIED for the
 first process. I'm going to check the rights of this process. Currently I
 have no clue why the access rights are different for the two processes.
