So I've got this 4 year old PC currently running Windows 10 right now. It is running Windows 10 because the Windows 8 license key I got for it 4 years ago did the free OS upgrade back when Windows 10 was released. It is now 2018 and the free upgrade is no longer available, I'm about to do a full wipe on the SSD in which the Windows is installed on, I'll be using the same license key from 4 years ago, my question is: is the Windows 10 upgrade permanently linked to my license key or no? If I reinstall windows using that license key will I be able to get Windows 10 again or Windows 8?
