Cortana promises to outshine other digital assistance suites by delivering exceptional compatibility with third-party apps. That means we’re not witnessing the full power of the blue-hued digital assistant just yet, but there are still some basic things everyone should set up to get the most out of Cortana

Most of the Cortana program’s essential settings can be configured in Windows 10’s Notebook. Notebook is available from the Start menu when Cortana is running. To access it, start Cortana, click the Windows icon in the bottom left to expand the start menu, and then click the notebook icon, which is located below the home icon on the left of the menu.

The final thing you should do here is enable and configure the “Hey Cortana” feature, which will listen for your voice or respond to anyone’s voice in general. This will allow you to give Cortana verbal commands without clicking or tapping.
