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

This Microsoft support page gives you details for older versions.

You could implement the code and run it on a Vista and Windows-7 machine to check the values returned.

Answer 2

I think you're looking for the GetVersionEx function.

Answer 3

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;
}

Answer 4

Similar to other tests for checking the version of Windows NT:

OSVERSIONINFO vi;

memset (&vi, 0, sizeof vi);
vi .dwOSVersionInfoSize = sizeof vi;
GetVersionEx (&vi);
if (vi.dwPlatformId == VER_PLATFORM_WIN32_NT  &&  vi.dwMajorVersion >= 6)

Answer 5

You could use the GetVersion() or GetVersionEx() function in the kernel32.dll. This two functions are only available on Windows 2000 or later.
