#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");}
