It was officially released, along with an i OS version, in December 2015. Microsoft's Cortana assistant is deeply integrated into its Edge browser.
Cortana can find opening-hours when on restaurant sites, show retail coupons for websites, or show weather information in the address bar.
At the Worldwide Partners Conference 2015 Microsoft demonstrated Cortana integration with upcoming products such as Gig Jam.

In May 2017, Microsoft in collaboration with Harman Kardon announced INVOKE, a voice-activated speaker featuring Cortana.
