我正在编写一个C ++代码来确定它运行的操作系统。我使用GetVersionEx() API来执行此操作，并使用this code作为教程，但它似乎无法处理Windows 8.是否有人知道如何修复它以在Windows 8下运行？

好的，我希望有人已经这样做了......但是，我猜不是，所以你走了：
Windows 8 Consumer Preview
//OSVERSIONINFO for GetVersionEx returns:
dwMajorVersion = 6;
dwMinorVersion = 2;
wProductType = 1;
//GetProductInfo returns:
dwType = 0x4A; //Not documented yet???
PS。我没有安装VS IDE。不得不做一个小应用程序来获得那些...

Windows 8是6.2 Windows Server 2012也是6.2 请参阅：http://msdn.microsoft.com/en-us/library/windows/desktop/ms724834(v=vs.85).aspx
答案 4 :(得分：1)
根据this MSDN page，实际上建议使用版本助手功能而不是GetVersionInfoEx来确定正在运行的Windows版本。如GetVersionEx页面所述，该API可能会在将来消失。
答案 5 :(得分：1)
系统的基本（主要，次要）验证的另一种可能的方法是检查核心系统文件的版本，例如kernel32.dll。
在GetFileVersionEx上使用另一个线程的信用......
