Microsoft engineers are busy toiling to put in the final touches in the latest version of Windows operating system, termed Windows 10. This operating system is being heralded as the attempt to unify the various Microsoft platforms (desktop, mobile, and Xbox) with the same foundational core.

The new “One Windows” platform provides the foundation to having a universal core for the various surfaces that run Microsoft operating systems today. The platform under the hoods of Windows 10 allows developers to write one app and have it run on every Windows device—be it the PC, tablet, phone, or Xbox console. This is intended to support even the yet-to-be-released devices like the HoloLens, Surface Hub, and Raspberry Pi 2 running Windows.

Not only will the apps be truly universal, even the store experience is going to be single. There will only be one store for app acquisition, distribution, and updates.

Microsoft’s vision for the “One Windows” platform was seeded in its attempt to do the following:

  • Drive scale through reach across device types
  • Deliver unique experiences
  • Maximize developer ROI

Today’s users are increasingly mobile first. Windows 10 is designed to allow customers to take full advantage of the all the screens in their life.

Windows 10’s adaptive UX allows the applications to adapt at runtime based on device capabilities and how the user is interacting with the app. To support this, the ViewStateManager has been updated to support more experiences. Developers no longer need to make separate application projects in Visual Studio. Instead, they only will need to make one project and it will support all surfaces.

Windows 10 also enables Cortana integration, allowing developers to integrate their applications with Microsoft’s virtual assistant.

What About HTML Developers?

HTML developers also have lots of advances to cheer for. The new rendering engine no longer requires developers to author platform-specific work to build a consistent mobile experience. This new engine is included in Internet Explorer 11 and in the new “Project Spartan” browser. The “Project Spartan” browser is itself a Windows app available from the Windows Store.

Windows 10 also makes it easy to package your website into an app that you can publish in the Windows Store. Calling Universal APIs is now supported from JavaScript, which enables building a more engaging user experience.
