Cortana
Cortana is Microsoft's new version of Siri. By using voice commands you can use this digital assistant to make appointments, know stock information or sports news, set reminders, and perform other standard search functions, typical for a smartphone. It can also be used to search the local hard drive and OneDrive.
Cortana can answer basic queries like “Will I need an umbrella tomorrow?” or "show me photos from January," and it will quickly run the search query. You can also ask how much it costs to attend Harvard University.
Users can also ask “Play my music” which will launche the music app.
