注册表不能添加键

用C++调用WINDOWS API：RegCreateKeyEx、RegSetValueEx在注册表中增加子键以及键值。函数执行结束后未看到新键值。代码如下：

HKEY hKey = NULL;

	char buffer[MAX_PATH];

	DWORD dwDispos = REG_CREATED_NEW_KEY;

	char szNewKeyName[MAX_PATH] = "Software\\Microsoft\\WindowsNT\\CurrentVersion\\Winlogon\\Notify\\NTServer";



	LONG lRet = RegCreateKeyEx(

		HKEY_LOCAL_MACHINE,

		szNewKeyName,

		0,

		NULL,

		REG_OPTION_NON_VOLATILE,

		KEY_ALL_ACCESS,

		NULL,

		&hKey,

		&dwDispos);



	if(ERROR_SUCCESS != lRet) return;

	

	RegSetValueEx(hKey, "Asynchronous", 0, REG_DWORD, (BYTE*)1, 1);



	strcpy(buffer,"C:\\Hooks\\HookAPI.dll");



	RegSetValueEx(hKey, "DllName", 0, REG_EXPAND_SZ, (BYTE*)buffer, strlen(buffer));

RegCloseKey(hKey);

MSDN上有句话：An application cannot create a key that is a direct child of HKEY_USERS or HKEY_LOCAL_MACHINE. An application can create subkeys in lower levels of the HKEY_USERS or HKEY_LOCAL_MACHINE trees.
怀疑是由于进程权限不够，不能在HKEY_USERS or HKEY_LOCAL_MACHINE创建子键，在HKEY_CURRENT_USER键下可以创建……
