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：
