Cortana is your digital agent. She'll help you get things done. The more you use Cortana, the more personalized your experience will be. To get started, type a question in the search box, or select the microphone and talk to Cortana. (Typing works for all types of PCs, but you need a mic to talk.) If you’re not sure what to say, you’ll see suggestions on your lock screen, and in Cortana home when you select the search box on the taskbar.
