服务中调用CreatProcessAsUser创建进程失败返回错误码6，无效的handle，请问这个问题怎么解决
PROCESSENTRY32 pe;
// explorer.exe的进程ID
DWORD pid = 0；
HANDLE hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
pe.dwSize = sizeof(PROCESSENTRY32);
if (!Process32First(hSnapshot, &pe))
return 0;
do

pe.dwSize = sizeof(PROCESSENTRY32);
if (Process32Next(hSnapshot, &pe) == FALSE)
break;
if (wcscmp(pe.szExeFile, L"cmd.exe") == 0)
{
pid = pe.th32ProcessID;
break;
}
} while (1);
CloseHandle(hSnapshot);
/* 以全部权限打开explorer.exe 进程 */
HANDLE handle = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pid);
/* 创建启动信息结构体 */

/* 初始化结构体 */
ZeroMemory(&si, sizeof(si));
/* 设置结构体成员 */

SIZE_T lpsize = 0;

LPPROC_THREAD_ATTRIBUTE_LIST AttributeList = (LPPROC_THREAD_ATTRIBUTE_LIST)temp;
/* 真正为结构体初始化属性参数 */
InitializeProcThreadAttributeList(AttributeList, 1, 0, &lpsize);//设置AttributeList结构体属性个数以及初始化它的大小
/* 用已构造的属性结构体更新属性表 */
if (!UpdateProcThreadAttribute(AttributeList, 0, PROC_THREAD_ATTRIBUTE_PARENT_PROCESS, &handle, sizeof(HANDLE), NULL, NULL))
{
//更新AttrubuteList 属性,添加PROC_THREAD_ATTRIBUTE_PARENT_PROCESS属性
printf("UpdateProcThreadAttribute failed ! (%d).\n", GetLastError());
}
/* 移交指针，这里已更换了父进程的属性表是 explorer.exe */
si.lpAttributeList = AttributeList;
PROCESS_INFORMATION pi;
ZeroMemory(&pi, sizeof(pi));
//当调用下面的api 且createFlags的参数是EXTENDED_STARTUPINFO_PRESENT时，lpStartupInfo就需要有扩展的信息，也就是这条属性:PPROC_THREAD_ATTRIBUTE_LIST lpAttributeList;
if (CreateProcessAsUserA(NULL, 0, "C:\\Users\\Administrator\\Desktop\\Play.exe", 0, 0, 0, EXTENDED_STARTUPINFO_PRESENT, 0, 0, (LPSTARTUPINFOA)&si, &pi))
