We've asked Microsoft if it can clarify this for us, though representatives previously declined to explain the term further.
Regardless, even if your PC becomes "unsupported" I would be surprised to see Microsoft cut off functionality or deny you access to your PC. It simply wouldn't fly if users suddenly lost all their family photos due to corporate greed or had to pay to fire up Chrome or save a Word document.
Instead, your PC would likely end up similar to Windows XP computers now: lacking feature updates, security patches, and the ability to install the latest and greatest third-party software.
What's more, bilking PC users for payments where none existed before is the kind of attitude that would encourage users to turn to Macs — or even, dare I say it, ponder a switch to Linux.
Bottom line, PC fans: Learn to stop worrying and love the Windows 10.
