content: Even if you got a free Windows 10 upgrade, it would have to do a fresh install and move your Vista stuff to windows.old and start over fresh with no apps and no settings left over from Vista.  Vista SP2 still has security updates until April 2017. No new features and no new service packs. You can't get the latest Internet Explorer or DirectX drivers either. You need Windows 8.1 and above for that now.
