Want Windows 10? You got it: for free. This is a sea change in Microsoft's strategy when it comes to upgrades. Gratis upgrades will be available for Windows 7, 8.1 and even Windows Phone 8.1 users for a full year.
Microsoft's Terry Myerson made the announcement with a vision of a more unified Windows: a world where asking "What version are you running" no longer makes sense. Giving everybody the latest version for free sounds like a good start. "We need our work in the hands of our customers," he said. Now if he'd only tell us when it'll be in our hands.
