G. Scott is thinking of putting Linux on an old computer. Leo says that's a great way to breathe new life into old hardware. Another option is Chrome OS. CloudReady is the site he'll want to use to get that done.
G Scott also wants to get Windows 10. Leo says to get a fresh stand alone version of Windows 10. When it installs, he'll be able to input his Windows 7 key to authenticate to Windows 10. That way he'll have the free Windows 10 upgrade. He can then downgrade if he wants and can upgrade it later.
