Check Windows version

Question

How I can check in C++ if Windows version installed on computer is Windows Vista and higher (Windows 7)?

Answer 1

Use GetVersionEx API function defined in kernel32.dll:

bool IsWindowsVistaOrHigher() {
   OSVERSIONINFO osvi;
   ZeroMemory(&osvi, sizeof(OSVERSIONINFO));
   osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
   GetVersionEx(&osvi);
   return osvi.dwMajorVersion >= 6;
}
