Faithful1, I'm assuming it will be a fee based service after one year. Maybe it will be a stand alone or bundled into the Office 365 product. Even if you bought a physical copy of Windows 10 it would be unsupported after a year - that's the message I'm getting from the offer. Giving the upgrade away for free is a way of getting people used to the idea of using the cloud for upgrades and purchases so eventually they can do away with selling any physical products. I've just accepted the fact that I won't "own" too many programs in the future but be subject to licensing agreements and mandatory updates that will wind up fixing one problem and creating a myriad of others.
