          微软在windows 10的版本号获取上留下一个坑，如果用GetVersionEx获取版本号，则获取到的是6.2.9200

      官方有如下说明

[GetVersionEx may be altered or unavailable for releases after Windows 8.1. Instead, use the Version Helper APIs]

      也就是8.1开始就不正常了，那么如何正常判断版本号呢，下面列举一下可用的三个方法吧

  1.manifest文件加上compatibility节点

<compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1"> 
        <application> 
            <!-- Windows 10 --> 
            <supportedOS Id="{8e0f7a12-bfb3-4fe8-b9a5-48fd50a15a9a}"/>
            <!-- Windows 8.1 -->
            <supportedOS Id="{1f676c76-80e1-4239-95bb-83d0f6d0da78}"/>
            <!-- Windows Vista -->
            <supportedOS Id="{e2011457-1546-43c5-a5fe-008deee3d3f0}"/> 
            <!-- Windows 7 -->
            <supportedOS Id="{35138b9a-5d96-4fbd-8e2d-a2440225f93a}"/>
            <!-- Windows 8 -->
            <supportedOS Id="{4a2f28e3-53b9-4441-ba9c-d69d4a4a6e38}"/>
        </application> 
    </compatibility>

2.通过系统文件来读取

这是win10 kernel32.dll文件的属性信息，看到没有，这里有版本信息

可以通过GetFileVersionInfo 来获取，具体实现就不讲了

3.使用微软推荐的Version Helper APIs来获取

函数是这个样子的：

IsWindows10OrGreater()

但是Requirements是这样的：

真相大白，其实就是调用ntdll里的RtlGetVersion函数来实现的。我们只需要拷贝一份这个头文件，直接调用相应的函数就可以了

贴一下这个头文件吧
