win10 系统版本号获取
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>
但是这种方法局限性比较大，如果只是开发静态库什么的，就不可行
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：
Minimum supported client
Windows 10 Technical Preview [desktop apps only]
Minimum supported server
Windows Server Technical Preview [desktop apps only]
Header
VersionHelpers.h (include Windows.h)
需要windows 10以后才可用,老版本的系统怎么用呢
是不是只有win10下的kernel32.dll才导出了这个函数呢，是不是需要动态获取这个函数来判断?
用IDA看了一下win10 kernel32.dll的导出函数，没看到有这个函数，猜测应该是由头文件来实现的，于是找来一份VersionHelpers.h
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
