Question

如何获取所有Windows的操作系统版本，至少是win95,98，me，xp，vista，7的名称？

我正在使用visual c ++ 2010，我想在纯win32应用程序中包含此功能。

Answer 1

使用GetVersionEx http://msdn.microsoft.com/en-us/library/ms724451%28v=VS.85%29.aspx

这样的事情怎么样：

#include <windows.h>
#include <string>
#include <lm.h>
#pragma comment(lib, "netapi32.lib")

bool GetWinMajorMinorVersion(DWORD& major, DWORD& minor)
{
    bool bRetCode = false;
    LPBYTE pinfoRawData = 0;
    if (NERR_Success == NetWkstaGetInfo(NULL, 100, &pinfoRawData))
    {
        WKSTA_INFO_100* pworkstationInfo = (WKSTA_INFO_100*)pinfoRawData;
        major = pworkstationInfo->wki100_ver_major;
        minor = pworkstationInfo->wki100_ver_minor;
        ::NetApiBufferFree(pinfoRawData);
        bRetCode = true;
    }
    return bRetCode;
}


std::string GetWindowsVersionString()
{
    std::string     winver;
    OSVERSIONINFOEX osver;
    SYSTEM_INFO     sysInfo;
    typedef void(__stdcall *GETSYSTEMINFO) (LPSYSTEM_INFO);

    __pragma(warning(push))
    __pragma(warning(disable:4996))
    memset(&osver, 0, sizeof(osver));
    osver.dwOSVersionInfoSize = sizeof(osver);
    GetVersionEx((LPOSVERSIONINFO)&osver);
    __pragma(warning(pop))
    DWORD major = 0;
    DWORD minor = 0;
    if (GetWinMajorMinorVersion(major, minor))
    {
        osver.dwMajorVersion = major;
        osver.dwMinorVersion = minor;
    }
    else if (osver.dwMajorVersion == 6 && osver.dwMinorVersion == 2)
    {
        OSVERSIONINFOEXW osvi;
        ULONGLONG cm = 0;
        cm = VerSetConditionMask(cm, VER_MINORVERSION, VER_EQUAL);
        ZeroMemory(&osvi, sizeof(osvi));
        osvi.dwOSVersionInfoSize = sizeof(osvi);
        osvi.dwMinorVersion = 3;
        if (VerifyVersionInfoW(&osvi, VER_MINORVERSION, cm))
        {
            osver.dwMinorVersion = 3;
        }
    }

    GETSYSTEMINFO getSysInfo = (GETSYSTEMINFO)GetProcAddress(GetModuleHandle(L"kernel32.dll"), "GetNativeSystemInfo");
    if (getSysInfo == NULL)  getSysInfo = ::GetSystemInfo;
    getSysInfo(&sysInfo);

    if (osver.dwMajorVersion == 10 && osver.dwMinorVersion >= 0 && osver.wProductType != VER_NT_WORKSTATION)  winver = "Windows 10 Server";
    if (osver.dwMajorVersion == 10 && osver.dwMinorVersion >= 0 && osver.wProductType == VER_NT_WORKSTATION)  winver = "Windows 10";
    if (osver.dwMajorVersion == 6 && osver.dwMinorVersion == 3 && osver.wProductType != VER_NT_WORKSTATION)  winver = "Windows Server 2012 R2";
    if (osver.dwMajorVersion == 6 && osver.dwMinorVersion == 3 && osver.wProductType == VER_NT_WORKSTATION)  winver = "Windows 8.1";
    if (osver.dwMajorVersion == 6 && osver.dwMinorVersion == 2 && osver.wProductType != VER_NT_WORKSTATION)  winver = "Windows Server 2012";
    if (osver.dwMajorVersion == 6 && osver.dwMinorVersion == 2 && osver.wProductType == VER_NT_WORKSTATION)  winver = "Windows 8";
    if (osver.dwMajorVersion == 6 && osver.dwMinorVersion == 1 && osver.wProductType != VER_NT_WORKSTATION)  winver = "Windows Server 2008 R2";
    if (osver.dwMajorVersion == 6 && osver.dwMinorVersion == 1 && osver.wProductType == VER_NT_WORKSTATION)  winver = "Windows 7";
    if (osver.dwMajorVersion == 6 && osver.dwMinorVersion == 0 && osver.wProductType != VER_NT_WORKSTATION)  winver = "Windows Server 2008";
    if (osver.dwMajorVersion == 6 && osver.dwMinorVersion == 0 && osver.wProductType == VER_NT_WORKSTATION)  winver = "Windows Vista";
    if (osver.dwMajorVersion == 5 && osver.dwMinorVersion == 2 && osver.wProductType == VER_NT_WORKSTATION
        &&  sysInfo.wProcessorArchitecture == PROCESSOR_ARCHITECTURE_AMD64)  winver = "Windows XP x64";
    if (osver.dwMajorVersion == 5 && osver.dwMinorVersion == 2)   winver = "Windows Server 2003";
    if (osver.dwMajorVersion == 5 && osver.dwMinorVersion == 1)   winver = "Windows XP";
    if (osver.dwMajorVersion == 5 && osver.dwMinorVersion == 0)   winver = "Windows 2000";
    if (osver.dwMajorVersion < 5)   winver = "unknown";

    if (osver.wServicePackMajor != 0)
    {
        std::string sp;
        char buf[128] = { 0 };
        sp = " Service Pack ";
        sprintf_s(buf, sizeof(buf), "%hd", osver.wServicePackMajor);
        sp.append(buf);
        winver += sp;
    }

    return winver;
}

Answer 3

查看MSDN文章 Getting the System Version

虽然本文仅提及当前支持的Windows版本，但请参阅此knowledge base article，了解您将在OSVERSIONINFO结构中为Win 95,98等看到的数字。

Answer 4

这完全取决于您需要了解操作系统版本的原因：

使用旧操作系统中可能无法使用的某些功能。在这种情况下，我强烈建议使用LoadLibrary和{{3来检查API本身是否可用}} 功能。否则，我猜您可以从ntdll.dll动态导入GetProcAddress并使用它，但同样，它有太多方法可以返回不准确的信息（想到的是兼容模式和 API trampolines ，可以通过恶意软件，AVP甚至操作系统本身安装。）
仅供显示。（例如：在您的应用的About窗口中，或将其包含在您的诊断事件日志中等）。在这种情况下快速而 hack 就是从系统注册表中将其作为文本阅读：

RtlGetVersion

这种方法的缺点是，名称和数字可以为最终用户的系统进行本地化。

使用自Windows XP以来可用的以下密钥：

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion

及其以下REG_SZ（或字符串）值：

ProductName =操作系统名称
CurrentVersion =操作系统版本
BuildLab =完整版号
BuildLabEx =扩展内部版本号（自Windows 7以来可用）
ReleaseId =版本号（自Windows 10起可用）
