Obviously, this package contains only the updated demo versions of Quake II (which are very engaging and addictive) but if you want to play the full version of Quake II, then you can either buy Quake II from Steam (which comes with all the updated files so that you can play it on Windows 10) or you can use your old Quake II CD from 1997 which contains old files that might not work in Windows 10. You can start playing Quake II on your computer without any trouble.
