Microsoft has announced that the Xbox One streaming feature is now available to PCs running on the Windows 10 preview. This allows the PC to mirror the entire Xbox One system, including accessing apps and the Xbox home screen. That being said, it still does not allow the streaming of movies from the Xbox One.
The whole ability to stream from one Windows machine to another has been a major feature for the upcoming Windows 10, and Microsoft has been keen to include the Xbox into the whole deal. At the moment, it looks like PCs will be able to access all the games on the Xbox. A couple of extra features appear to include a pseudo-split screen between the PC and Xbox. This essentially means that split screen games will instead display one player on the TV, with the other streamed to the connected PC.
Unfortunately, this streaming feature still lacks a few things. It does not yet have support for keyboard and mouse for the Xbox One interface. Although it appears that Microsoft does not intend to ever allow keyboard and mouse input for the feature, which is quite a disappointment. Or it would be if Microsoft ever decided to officially bring the Xbox to Malaysia. That being said, this is probably a good excuse to pick up the gorgeous Xbox One Elite controller.
