获取Windows系统版本

 

语言:C/C++
编程软件:VS2015
字符集:UNICODE编码

【1】说明

1、由于GetVersionEx函数在Windows 8.1版本之后,返回的结果全部是6.2,这函数被微软动了手脚的,但是实际上可以利用额外添加一个manifest文件指示兼容新版本.

(参看文章:http://blog.csdn.net/k1988/article/details/47614529)

2、GetVersionEx函数还有一个问题,就是当使用兼容模式打开程序时,它返回的是兼容模式下的系统版本号.

由于以上这两个问题,建议用Version Helper系列的函数或使用直接内核的函数获取系统版本信息.

这里直接使用ntdll.dll里的函数,获取系统版本信息.

	BOOL Wow64;
	SYSTEM_INFO info;
	//判断是否是在64位系统模拟层上运行
	if (!IsWow64Process(GetCurrentProcess(), &Wow64))
		return FALSE;
	//获取CPU信息
	if (Wow64)
		GetNativeSystemInfo(&info);
	else
		GetSystemInfo(&info);
	//定义变量
	typedef LONG(__stdcall *fnRtlGetVersion)(PRTL_OSVERSIONINFOW lpVersionInformation);
	fnRtlGetVersion pRtlGetVersion;
	HMODULE hNtdll;
