12. Powerful natural language search
Cortana can handle all sorts of commands you issue using natural language, such as playing music, creating reminders, showing the weather, or even remembering random facts for you, but the most powerful use of her natural language abilities revolves around basic search capabilities. You can give Cortana basic commands like “Find pictures from June” or “Find documents with Windows 10” and she’ll apply the appropriate filters, then scour your local files and ONEDRIVE storage for results.
You can now enable Cortana on the Windows lock screen as well, where you can use voice commands to view and edit your schedule at a glance. To turn on the feature, open Cortana and head to ‘Cog’ icon > Settings > Use Cortana even when my device is locked.
