Cortana is the new digital personal assistant that comes as a feature with Windows 10. It's a really helpful way to find information by typing in a search query or just by speaking naturally if you have a microphone enabled.
October 2017 Update:
Microsoft have made it increasingly difficult to disable Cortana within Windows 10 and there is no way to disable it without getting your hands dirty. This process from @Regedit32 is currently the easiest way to disable Cortana:
-----------------------------------
Press Enter key
Type exit and press Enter key to close the console
Now press the following three keys together: Ctrl + Shift + Esc to open Task Manager
Scroll to bottom of Task Manager window and right-click on Windows Explorer and select Restart
You screen and taskbar with darken and flash for a moment, then return to normal. At this point close the Task Manager window.
Cortana ought now be stopped and a normal search in its place.
