What's New in Windows 10

Microsoft revealed a number of new details about Windows 10 during its Build developer conference in San Francisco this week.
Between a closer look at Cortana's new abilities, new ways for developers to bring their apps to Windows, and finally giving the new "Project Spartan" browser a name, we learned much more about how Windows 10 will work on phones, tablets, PCs, wearables and more.
For instance, Windows 10 is coming this summer to PCs, and everything else later.
