content: "Microsoft’s Windows 10 message hasn’t always been clear. They’ve declared the Windows 10 upgrade will be free for the first year and that going forward they’ll be pushing “Windows 10 as a service." This is how the article you linked started. I don't understand how you translate "free for the first year" to "free for ever". Am I missing something? edit:"This is more than a one-time upgrade: once a Windows device is upgraded to Windows 10, we will continue to keep it current for the supported lifetime of the device – at no cost."Sorry for the misinterpretation, here is a microsoft page confirming what you are saying.
