  1. To use function WinAPI GetVersion or GetVersionEx. The following function returns true if the program is launched on NT:
    bool isNT () 
{ 
OSVERSIONINFO ver_info; 
ver_info.dwOSVersionInfoSize = sizeof (OSVERSIONINFO); 
GetVersionEx (&ver_info); 
return (ver_info.dwPlatformId == VER_PLATFORM_WIN32_NT); 
}

  2. To check up value of global variable Win32Platform. Possible variants of values:
    • VER_PLATFORM_WIN32_NT - The program is fulfilled under control of OS of line WinNT (Windows NT/2000/XP)
    • VER_PLATFORM_WIN32_WINDOWS - The program is fulfilled under control of OS of line Win9x (Windows 95/98/Me)
    • VER_PLATFORM_WIN32s - The program is fulfilled under control of OS Windows 3.1 with installed Win32s extension
