现在很多软件都有统计系统了，说好听点叫做统计用户习惯，改良产品，不好听点，呵呵，我就不说了。
核心我已经封装成类了，可以获取操作系统版本，MAC地址，本地IP地址，以及判定是否为网吧。
核心代码如下：

//PCInfo.h

#pragma once
#include <string>

class CPCInfo
{
public:
        CPCInfo(void);
        ~CPCInfo(void);
private:
        // 获取MAC地址
        std::string& GetMAC();
        // 获取IP地址
        std::string& GetIP();
        // 获取操作系统
        std::string& GetOS();
        // 是否为网吧
        bool IsInternetBar();
public:
        std::string m_strIP;
        std::string m_strMAC;
        std::string m_strOS;
        bool m_bIsInternetBar;
};
