The next public release of Windows 10 will include Project Spartan, Microsoft’s lightweight Internet Explorer replacement. Kevin Gallo, Microsoft’ technical lead for Windows universal apps, confirmed the news during Mobile World Congress.

It’s not entirely clear when the next technical preview will arrive although sources tell The Verge that it should happen by the end of this month.

The Redmond-based company also for the first time demonstrated Windows 10 universal apps running on an Xbox One. While not specific, the publication said it wasn’t an app like Mail or Photos, but rather one designed to run across multiple platforms.

The idea behind Gallo’s demonstration wasn’t to show a specific app running on Xbox One but to drive home the bigger picture of universal apps.

In a recent blog post on the matter, Gallo said the platform enables a new class of Windows universal apps that are truly written once, with one set of business logic and one UI. Microsoft wants universal apps to feel consistent and familiar to the customer across all devices whether it is mobile, desktop, console, holographic or IoT devices.

In order to pull off that consistent feel, Windows 10 will determine (at runtime) how the user is interacting with an app and render the appropriate UI. For example, on a laptop with a touch-screen, an app fly-out control will provide larger touch targets if tapped with touch, as opposed to clicked with a mouse.
