                                 WM_SETTINGCHANGE,

                                 SendMessageTimeoutFlags.SMTO_NORMAL,
                                 1000,
                                 out result);
            return result;
        }
    }
}

以上代码 是在网上查找到的 不过我在本机上测试 执行该函数 一直卡主超时，操作系统为Win7 64位，求测试 ，求修改注册表后不重启立即生效的方法！！！
