How about something like this:
这样的事情怎么样：

major = pworkstationInfo->wki100_ver_major;

Take a look at the MSDN article Getting the System Version
看一下MSDN文章获取系统版本
While the article only mentions currently supported Windows versions, see this knowledge base articlefor the numbers you'll see in the OSVERSIONINFO structure for Win 95, 98 etc.
虽然该文章仅提及当前支持的 Windows 版本，但请参阅此知识库文章，了解您将在 Win 95、98 等的 OSVERSIONINFO 结构中看到的数字。

It all depends on why you need to know OS version:
这完全取决于您为什么需要知道操作系统版本：
To use certain feature that may not be available in older OS.In this case I would strongly suggest checking if the API itself is available using LoadLibraryand GetProcAddressfunctions. Otherwise, I guess you can dynamically import RtlGetVersionfrom
ntdll.dlland use it, but again, there're too many ways it can return inaccurate information (the ones that come to mind are compatibility mode and API trampolinesthat can be installed by malware, AVP, and even OS itself.)For display purposes only.(ex: in
Aboutwindow for your app, or to include it in your diagnostic event log, etc.) In this case a quick and easy hackis to read it as text from the System Registry:
使用旧操作系统中可能不可用的某些功能。在这种情况下，我强烈建议使用LoadLibrary和GetProcAddress函数检查 API 本身是否可用。否则，我想你可以动态导入RtlGetVersion从
ntdll.dll和使用它，但同样，有太多种方法可以返回不准确的信息（即脑海中出现兼容模式和那些API蹦床，可以通过恶意软件，AVP进行安装，甚至操作系统本身。）仅用于展示目的。（例如：在
About您的应用程序的窗口中，或将其包含在您的诊断事件日志中等）在这种情况下，一个快速而简单的技巧是从系统注册表中将其作为文本读取：
The downside of this approach though, is that the names and numbers can be localized for the end-user's system.
但是，这种方法的缺点是可以为最终用户的系统本地化名称和号码。
Use the following key that is available since Windows XP:
使用自 Windows XP 起可用的以下密钥：
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
and its following REG_SZ(or string) values:
及其以下REG_SZ（或字符串）值：
ProductName= for OS nameCurrentVersion= for OS versionBuildLab= for full build numberBuildLabEx= extended build number (available since Windows 7)ReleaseId= Release number (available since Windows 10)
ProductName= 操作系统名称CurrentVersion= 操作系统版本BuildLab= 完整版本号BuildLabEx= 扩展版本号（自 Windows 7 起可用）ReleaseId= 版本号（自 Windows 10 起可用）
