windows通过c++获取操作系统主要分两种：
1、windows是8.1版本以下版本：获取操作系统可以通过windows提供的api中GetVersionEx函数来获取
2、windows是8.1版本及以上：获取操作系统主要通过RtlGetNtVersionNumbers法来获取
代码如下：
#include <Windows.h>
#include <string>
#include <iostream>
#define WINVERSION_2012 4026541440 //Microsoft Windows Server 2012 R2 的BuildNumber号
#define WINVERSION_10 4026546233 //Microsoft Windows 10 的BuildNumber号
using namespace std;
