【实例简介】

先开启热点，再选择当前的有线网卡（选择有网的wifi也可以），开启网络共享，即可实现wifi共享上网。
如果手机连上了热点却没有网，把手机的wifi关掉，重新连一遍就好了。
如果热点开着手机却连不上，点“关闭热点”，再点“开启热点”就好了。
如果连接校园网的时候提示“IP地址错误”，点“停止共享”，再登录校园网客户端就好了。
如果校园网上不了IPv6，选择好有线网卡，点“禁用”，然后退出校园网客户端，再点“启用”，重新登录校园网客户端就好了。
Windows的ICS服务偶尔会出Bug，如果无法开启热点，可以尝试 “说明...”->“重新启动ICS服务”

点击“关闭窗口”，程序会保留在后台，下次打开时不会弹出“管理员权限确认”窗口。
点击“退出程序”，程序会直接退出，下次打开时会弹出“管理员权限确认”窗口。
（本人觉得这样很麻烦，所以有保留在后台的功能）
