'/*=========================================================================  
' * Intro    网上找了一圈，都不怎么好，有一个比较不错的，汉化作者汉化时加了个自己的介绍文件，这个文件比程序本身还大，感觉不爽，于是本人的VBS版MAC修改代码便诞生了,在使用过程中如果出现不能上网的情况得返回一下网卡驱动（有些机器比较特别），如果要返回以前的MAC可以：开始-->控制面板-->网络连接-->点击您的网卡(一般是"本地连接")-->点击常规里的属性-->配置..-->高级-->选中-->NetworkAddress-->右边选择"不存在"
