Microsoft company are making their first tests of Cortana Personal Assistant that is already on all Windows Phone smartphones, now on Windows 10 for Desktops.
The video below is a Pre-release test and some features are not yet complety working , however it is a good beginning, some of the basic request are responding as you can expect.
"Cortana in this form does not represent the final product. The UI, among many other things are not finished in the build we have access to, so Cortana will look ten times better by the time she is unveiled to the public.
From the get go, Cortana can do pretty much everything the Windows Phone version can. This includes reminders, call people with skype, check my location/maps, play/pause music, launch apps, check the weather and more. Right now, Cortana doesn't have a personality in Windows 10, meaning she doesn't answer questions like "Who are you", however we have it on good authority that she will have this ability by the time she rolls out to the public."
But please watch the video and make yourself an opinion.
As for Windows 10, expect Cortana to be up and ready for the stable version of the operating system which, according to Microsoft’s own statements, should arrive in late summer 2015 or early fall. More details could, however, be provided in April 2015 at he BUILD conference, when a developer preview of Windows 10 could also be presented.
