Windows 10 offers a feature that lets the operating system and Cortana, get to know and recognize your voice and writing, so that it can make better suggestions to you. It does so by collecting information like handwriting patterns, speech variations, calendar events, contacts and so on. If you do not want this to happen and would like to stop Windows 10 and Cortana getting to know you you can turn off or disable this feature.
