//复制一下内容到文本中，改名文本为WindowsVersion.h，这样就可以在你的程序中调用BOOL DisplaySystemVersion(LPTSTR buffer)函数了，当然包含头文件了；

//下面的函数其实也不是原创了，这里我简单添加了一些定义，这样这个文件就可以在VC6中应用了；

这里还有一个更简单的函数判断系统是否为win7：

bool isWin7()
{
OSVERSIONINFOEX osvi;
    BOOL bOsVersionInfoEx;

ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
    osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
    bOsVersionInfoEx = GetVersionEx((OSVERSIONINFO*) &osvi);

// win7的系统版本为NT6.1
    if ( VER_PLATFORM_WIN32_NT == osvi.dwPlatformId &&
        osvi.dwMajorVersion == 6 &&
        osvi.dwMinorVersion == 1 )
    {
        return true;
    }
else
{
  return false;
}
}
