TDIfw在windows 10 1903的测试最近看了一下TDI的网络过滤驱动，在Vista之后就不支持了，但是据说windows7还是能用，于是想试试在win10上还能不能玩。需要注意的是在win10上的TCP和UDP设备对象的驱动对象变成了tdx，于是有了下面的代码。

我是靠谱客的博主 呆萌鸡，最近开发中收集的这篇文章主要介绍TDIfw在windows 10 1903的测试最近看了一下TDI的网络过滤驱动，在Vista之后就不支持了，但是据说windows7还是能用，于是想试试在win10上还能不能玩。需要注意的是在win10上的TCP和UDP设备对象的驱动对象变成了tdx，于是有了下面的代码。，觉得挺不错的，现在分享给大家，希望可以做个参考。

经过测试无法在打开ie的时候无法拦截到connect请求，但是如果关闭网卡之后在打开，可以看到IRP_MJ_CREATE和IRP_MJ_INTERNAL_DEVICE_CONTROL（TDI_ASSOCIATE_ADDRESS）的消息，由于技术有限也不知道是不是姿势不对还是说windows真的改了。
