As part of Cortana’s recent evolution, we’ve made some changes to where you can access lists and reminders after you upgrade to the latest version of Windows 10, in markets other than English (United States).
If you previously created a shopping list or a reminder in Cortana, you can now find that information on your PC or mobile device in the Microsoft To Do app.
And if you were accustomed to creating alarms or timers with Cortana, you can now use the alarms & clock app on your PC to help keep your day on track.
