完全实现注册表处理，文件处理。服务端采用多线程服务，能最好的处理SOCKET请求。数据接收、发送函数可以说是现阶段最好的，采用异步重叠操作。可以取得被控机器上的硬件信息，文件信息，注册表以及进行屏幕控制。 代码中的SOCKET重叠I/O的实现也很值得参(complete registry handling, document handling. Server using multithreading services will best address SOCKET request. Data reception, sending function can be said at this stage the best, using asynchronous overlapping operations. Machines can get charged with the hardware information, document information, registry and control for the screen. SOCKET code of overlapping I/O is also the realization worth Participation)
