如何检测在调用InitiateSystemShutdownW之后是否安排了重启？

bool IsRestartScheduled()
{
    DWORD shutdownFlags = GetSystemMetrics(SM_SHUTTINGDOWN);
    return (shutdownFlags & 0x2000) != 0;
}

bool IsRestartScheduled()
{
    IWbemLocator* pLocator = nullptr;
    IWbemServices* pServices = nullptr;
    IEnumWbemClassObject* pEnum = nullptr;
    IWbemClassObject* pObject = nullptr;

    bool isRestartScheduled = false;

    if (SUCCEEDED(CoInitialize(nullptr)))
    {
        if (SUCCEEDED(CoCreateInstance(CLSID_WbemLocator, nullptr, CLSCTX_INPROC_SERVER, IID_IWbemLocator, (LPVOID*)&pLocator)))
        {
            if (SUCCEEDED(pLocator->ConnectServer(L"ROOT\\CIMV2", nullptr, nullptr, nullptr, 0, nullptr, nullptr, &pServices)))
            {
                if (SUCCEEDED(pServices->ExecQuery(L"WQL", L"SELECT * FROM Win32_OperatingSystem", WBEM_FLAG_FORWARD_ONLY, nullptr, &pEnum)))
                {
                    ULONG uReturned = 0;
                    while (pEnum->Next(WBEM_INFINITE, 1, &pObject, &uReturned) == S_OK)
                    {
                        VARIANT var;
                        if (SUCCEEDED(pObject->Get(L"RebootRequired", 0, &var, nullptr, nullptr)))
                        {
                            isRestartScheduled = (var.boolVal == VARIANT_TRUE);
                            VariantClear(&var);
                        }

                        pObject->Release();
                    }
                }
            }
        }
    }

    if (pLocator)
        pLocator->Release();
    if (pServices)
        pServices->Release();
    if (pEnum)
        pEnum->Release();

    CoUninitialize();

    return isRestartScheduled;
}
