IWbemClassObject Get成功，而Put with Error：ERROR_SXS_KEY_NOT_FOUND 140007

Question

代碼的主要目標是自定義虛擬內存頁面文件的InitialSize和MaximumSize。

ENV：Windows Server 2008的

代碼：

... 
... 
IWbemClassObject* pclsObj = NULL; 
ULONG uReturn = 0; 

while(pEnumerator) 
{ 
    HRESULT hr = pEnumerator->Next(WBEM_INFINITE,1, &pclsObj, &uReturn); 
    VARIANT initial_size; 
    VARIANT maximum_size; 


    //InitialSize 
    pclsObj->Get(L"InitialSize", 0, &initial_size, 0, 0); 

    //get the maximumsize of the pagefile 
    //MaximumSize 
    pclsObj->Get(L"MaximumSize", 0, &maximum_size, 0, 0); //successfully 


    //use the put to adjust the pagefile size 

    VARIANT in_initialsize; 
    VariantInit(&in_initialsize); 
    in_initialsize.vt = VT_I4; 
    in_initialsize.iVal = 13000; 

    //set the initialsize of the pagefile 
    hr = pclsObj->Put(L"InitialSize", 0, &in_initialsize, 0); //failed with 14007 
     ... 
     ... 
} 
...

使用另一種解決方案，來獲得實例GetObject，最後。必須執行Put操作;如下所示：

... 
l_pSVC->PutInstance(l_pinObj, WBEM_FLAG_UPDATE_ONLY, NULL, NULL);
