个人不建议用 GetVersion 或GetVersionEx 之类的 API 来获取系统版本号。注意微软也说过，这个结果会受到兼容模式的影响，即如果程序设置兼容模式为 XP 那么拿到的也可能是 5.1 的。所以要准确的获取版本号，我建议直接获取 kernel32.dll 的主版本号，这个是和系统的版本号是一样的。

下面是我写的一个获取windows版本信息的两个函数，供大家参考：

// 具体版本信息参考Operating System Version https://msdn.microsoft.com/en-us/library/ms724832.aspx
    enum enOsInfo
    {    
    OS_UNKNOWN = 0, // 未知的操作系统
    OS_WIN_NT_3_5, // win nt 4.0,1996年7月发布 
    OS_WIN_95,   // win 95
    OS_WIN_98,
    OS_WIN_ME, // windows me
        OS_WIN_2000,
    OS_WIN_XP,
    OS_WIN_XP_64, // win xp 64位
    OS_WIN_SERVER2003,
        OS_WIN_SERVER2003_R2,
    OS_WIN_VISTA,
    OS_WIN_SERVER2008,
    OS_WIN_SERVER2008_R2,
    OS_WIN7,
    OS_WIN7_64,
    OS_WIN_SERVER2012,
        OS_WIN8, //6.2
    OS_WIN8_64,
    OS_WIN_SERVER2012_R2,
    OS_WIN8_1  // 6.3
    };
    
    bool GetWindowsVersion(int& nMajorVersion,int& nMinorVersion,int& nBuildVersion,int& nReviVersion)
    {
    TCHAR szDLLName[MAX_PATH] = { 0 };
    HRESULT hr = SHGetFolderPath(NULL, CSIDL_SYSTEM, NULL, SHGFP_TYPE_CURRENT, szDLLName);
    if (SUCCEEDED(hr) && PathAppend(szDLLName, _T("kernel32.dll"))) 
    {
    DWORD dwVerInfoSize = GetFileVersionInfoSize(szDLLName, NULL);
    if (dwVerInfoSize > 0) {
    LPVOID pvVerInfoData = (LPVOID)new BYTE[dwVerInfoSize];
    if (GetFileVersionInfo(szDLLName, 0, dwVerInfoSize, pvVerInfoData)) {
    UINT ulLength = 0;
    VS_FIXEDFILEINFO* pVsInfo = NULL;
    if (VerQueryValue(pvVerInfoData, _T("\\"), (LPVOID *)&pVsInfo, &ulLength)) 
    {
    nMajorVersion = HIWORD(pVsInfo->dwFileVersionMS);
    nMinorVersion = LOWORD(pVsInfo->dwFileVersionMS);
    nBuildVersion = HIWORD(pVsInfo->dwFileVersionLS);
    nReviVersion = LOWORD(pVsInfo->dwFileVersionLS);
    delete[] pvVerInfoData;
    return true;
    }
    }
    delete[] pvVerInfoData;
    }
    }
    return false;
    }
    
    enOsInfo GetOsInfo()
    {
            enOsInfo os_info =  OS_UNKNOWN;
    
    int nMajorVersion,nMinorVersion,nBuildVersion,nReviVersion;
