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：

VOID GetOSVersion(CString& strOSVersion)
{
OSVERSIONINFOEX osver = {0};
osver.dwOSVersionInfoSize = sizeof (osver);
::GetVersionEx((OSVERSIONINFO*)&osver);
if ( osver.dwMajorVersion == 5
&& (osver.dwMinorVersion == 1 || osver.dwMinorVersion == 2)
)
{
strOSVersion = L "OS:Windows XP" ;
}
else if (osver.dwMajorVersion == 6 && osver.dwMinorVersion == 0)
{
strOSVersion = L "OS:Windows Vista" ;
}
else if (osver.dwMajorVersion == 6 && osver.dwMinorVersion == 1)
{
strOSVersion = L "OS:Windows 7" ;
}
else if (osver.dwMajorVersion == 6 && osver.dwMinorVersion == 2)
{
strOSVersion = L "OS:Windows 8" ;
}
else if (osver.dwMajorVersion == 6 && osver.dwMinorVersion == 3)
{
strOSVersion = L "OS:Windows 8.1" ;
}
}
