windows系统的版本信息从OSVERSIONINFO 结构体获取，该结构体的详细定义如下：</span>

<pre name="code" class="cpp">typedef struct _OSVERSIONINFOA {    DWORD dwOSVersionInfoSize;    DWORD dwMajorVersion;//主版本号    DWORD dwMinorVersion;//次版本号    DWORD dwBuildNumber;    DWORD dwPlatformId;    CHAR   szCSDVersion[ 128 ];     // Maintenance string for PSS usage} OSVERSIONINFOA, *POSVERSIONINFOA, *LPOSVERSIONINFOA;

void GetSystemName(std::string &strOsName){SYSTEM_INFO info;        GetSystemInfo(&info);    OSVERSIONINFOEX os; os.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);   strOsName = _T("unknown OperatingSystem.");if(GetVersionEx((OSVERSIONINFO *)&os)){ switch(os.dwMajorVersion) {case 4:switch(os.dwMinorVersion) { case 0:if(os.dwPlatformId == VER_PLATFORM_WIN32_NT)strOsName =_T("Windows NT 4.0");  else if(os.dwPlatformId==VER_PLATFORM_WIN32_WINDOWS)strOsName =_T("Windows 95");break;case 10:strOsName =_T("Windows 98");break;case 90:strOsName =_T("Windows Me");break;}break;case 5:switch(os.dwMinorVersion) { case 0:strOsName =_T("Windows 2000"); break;case 1:strOsName =_T("Windows XP"); break;case 2:if(os.wProductType==VER_NT_WORKSTATION && info.wProcessorArchitecture==PROCESSOR_ARCHITECTURE_AMD64){strOsName =_T("Windows XP Professional x64 Edition");}else if(GetSystemMetrics(SM_SERVERR2)==0)strOsName =_T("Windows Server 2003"); else if(GetSystemMetrics(SM_SERVERR2)!=0)strOsName =_T("Windows Server 2003 R2");break;}break;case 6:switch(os.dwMinorVersion){case 0:if(os.wProductType == VER_NT_WORKSTATION)strOsName =_T("Windows Vista");elsestrOsName =_T("Windows Server 2008"); break;case 1:if(os.wProductType == VER_NT_WORKSTATION)strOsName =_T("Windows 7");elsestrOsName =_T("Windows Server 2008 R2");break;case 2:if(os.wProductType == VER_NT_WORKSTATION)strOsName =_T("Windows 8");elsestrOsName =_T("Windows Server 2012");break;case 3:if(os.wProductType == VER_NT_WORKSTATION)strOsName =_T("Windows 8.1");elsestrOsName =_T("Windows Server 2012 R2");break;}break;}} }
