Microsoft recently revealed that they will be releasing Office universal apps preview for Windows 10 for phones preview users later this month. A video demo of Windows 10 For Phones Build 12544 appeared online from Chinese forums. In this video, you can see the upcoming Office universal apps in action along with the redesigned Windows Store. There are also some changes in the Start Screen customization features, developer settings, and few other stuff. Unfortunately, the video is in Chinese making it difficult for us to understand. However, you can see them in action in the video above.
Thanks to Windowsblogitalia for the heads up!
