The Siri-dominating Cortana might be included in the final release of Windows 9. Microsoft’s virtual assistant has so far received a good deal of praise for its performance on Windows Phone 8.1.
According to a report from Neowin, Cortana has been upgraded from an engineering build to a more stable release cycle in the early builds of Windows 9. The latter could be pointing at the virtual assistant being included in the final release of the OS.
At this point, Cortana in early Windows 9 builds is a standalone app that takes up about 25% of the display, with the familiar animated circle located in the center. The app can take commands via voice or typing.
It is reasonable to expect that Cortana will be integrated into Windows 9 on a much deeper level than a standalone app in case Microsoft goes forward with its development. This demo video from Microsoft Research might be suggesting how.
