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 your Microsoft account (Outlook or Office 365) was linked to Cortana's notebook before upgrading to the latest version of Cortana, you can now find your lists and reminders 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.
