Microsoft has published a new video on its Windows Phone YouTube channel. This latest video is dedicated to helping consumers get comfortable with Cortana and using commands to obtain different pieces of information. The new virtual assistant is part of the Windows Phone 8.1 update, but is not yet available outside the US (unless you switch up your region and language settings).
There are a number of ways to interact with Cortana, as well as sharing interests and configuring the assistant to provide you with a more personalized experience. We've also covered Cortana in the past fairly extensively, so be sure to search through and find some handy articles to help you out. We'll list a handful below.
