Microsoft's big promise with Windows 10 is its ability to run apps across the entire platform. The framework for these universal apps hasn't been described in much detail, but a post on the Windows Blog gives a bit more insight under the hood. Redmond's calling these "mobile experiences," meaning apps you can use across a variety of different devices; the software is mobile, not the gizmo you're using it on. Cortana moving from smartphone to desktop and the Xbox One's Game DVR tool being available on your gaming PC are but a few examples. The idea is to offer a set of standards across the Windows 10 platform so everything remains familiar regardless of what piece of hardware you're accessing the application from. That means everything should have, in Microsoft's words, an adaptive user experience with natural inputs; calls for cloud-based services including Cortana integration and the action center and one design language across the board.
