GetVersionEx under Windows 8
GetVersionEx under Windows 8
我正在编写一个C++代码来确定它在什么操作系统上运行。我使用GetVersionEx() API来完成这项工作，这段代码作为教程，但它似乎无法处理Windows 8。有人知道如何修复它以在Windows8下运行吗？
根据MSDN论坛和本文中的几条评论，Windows 8的版本号是6.2
这是在Windows8开发者预览版中更新和测试的示例代码

操作系统版本Microsoft Windows开发者预览版内部版本号8102版本6.2.8102
在Windows 8开发人员预览版上。
好吧，我希望有人已经这么做了。。。但是，我想不会，所以给你：
Windows 8消费者预览版
//OSVERSIONINFO for GetVersionEx returns:
dwMajorVersion = 6;
dwMinorVersion = 2;
wProductType = 1;
//GetProductInfo returns:
dwType = 0x4A; //Not documented yet???
PS。我没有在那里安装VS IDE。必须制作一个小应用程序才能获得这些。。。
Windows 8版本为6.2。
Windows Server 2012也是6.2版本。
请参阅：http://msdn.microsoft.com/en-us/library/windows/desktop/ms724834（v=vs.85）.aspx
对系统进行基本（主要、次要）验证但不深入产品详细信息的另一种可能方法是检查核心系统文件的版本，例如kernel32.dll。
在GetFileVersionEx上使用的另一个线程的信用。。。

根据这个MSDN页面，实际上建议使用Version Helper函数而不是GetVersionInfoEx来确定运行的Windows版本。如GetVersionEx页所述，API可能在未来消失。
