本文提供了一个简单的C程序示例，用于检测当前运行的操作系统是否为Windows XP或更高版本。通过使用OSVERSIONINFO结构体并调用GetVersionEx函数，程序能够准确判断系统版本，并输出相应的信息。

摘于MSDN

#include <windows.h>
#include <stdio.h>

void main()
{
    OSVERSIONINFO osvi;
    BOOL bIsWindowsXPorLater;

    ZeroMemory(&osvi, sizeof(OSVERSIONINFO));
    osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);

    GetVersionEx(&osvi);

    bIsWindowsXPorLater = 
       ( (osvi.dwMajorVersion > 5) ||
       ( (osvi.dwMajorVersion == 5) && (osvi.dwMinorVersion >= 1) ));

    if(bIsWindowsXPorLater)
        printf("The system meets the requirements.\n");
    else printf("The system does not meet the requirements.\n");
}

OSVERSIONINFO结构体：

typedef struct _OSVERSIONINFO {
  DWORD dwOSVersionInfoSize;
  DWORD dwMajorVersion;
  DWORD dwMinorVersion;
  DWORD dwBuildNumber;
  DWORD dwPlatformId;
  TCHAR szCSDVersion[128];
} OSVERSIONINFO;

操作系统版本：

Operating system	Version number	dwMajor Version	dwMinor Version	Other
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 Server 2003	5.2	5	2	GetSystemMetrics(SM_SERVERR2) == 0
Windows XP	5.1	5	1	Not applicable
Windows 2000	5.0	5	0	Not applicable
