vc中获取windows版本信息，一般是调用GetVersionEx 这个API函数来获取的，这个API需要OSVERSIONINFOEX 这个结构体作为参数，OSVERSIONINFOEX 的对应的具体的OS版本类型详细如下：

Operating system	Version number	dwMajorVersion	dwMinorVersion	Other
Windows 8.1	6.3*	6	3	OSVERSIONINFOEX.wProductType == VER_NT_WORKSTATION
Windows Server 2012 R2	6.3*	6	3	OSVERSIONINFOEX.wProductType != VER_NT_WORKSTATION
Windows 8	6.2	6	2	OSVERSIONINFOEX.wProductType == VER_NT_WORKSTATION
Windows Server 2012	6.2	6	2	OSVERSIONINFOEX.wProductType != VER_NT_WORKSTATION
Windows 7	6.1	6	1	OSVERSIONINFOEX.wProductType == VER_NT_WORKSTATION
Windows Server 2008 R2	6.1	6	1	OSVERSIONINFOEX.wProductType != VER_NT_WORKSTATION
Windows Server 2008	6.0	6	0	OSVERSIONINFOEX.wProductType != VER_NT_WORKSTATION
Windows Vista	6.0	6	0	OSVERSIONINFOEX.wProductType == VER_NT_WORKSTATION
Windows Server 2003 R2	5.2	5	2	GetSystemMetrics(SM_SERVERR2) != 0
Windows Home Server	5.2	5	2	OSVERSIONINFOEX.wSuiteMask & VER_SUITE_WH_SERVER
Windows Server 2003	5.2	5	2	GetSystemMetrics(SM_SERVERR2) == 0
Windows XP Professional x64 Edition	5.2	5	2	(OSVERSIONINFOEX.wProductType == VER_NT_WORKSTATION) && (SYSTEM_INFO.wProcessorArchitecture==PROCESSOR_ARCHITECTURE_AMD64)
Windows XP	5.1	5	1	Not applicable
Windows 2000	5.0	5	0	Not applicable
* For applications that have been manifested for Windows 8.1. Applications not manifested for 8.1 will return the Windows 8 OS version value (6.2). To

 本人就获取 windows xp，vista，win8 ,win8.1 等系统版本信息 写了个函数，实现如下：
