To make your personal digital assistant as helpful as possible, we’re shifting how we integrate Cortana into your Microsoft 365 productivity apps. As part of our standard practice, we’re ending support for Cortana in older versions of Windows that have reached their end-of-service dates.
Although you’ll still be able to search your files or the web, we recommend that customers update their devices to continue using Cortana. You can access the Cortana content you created previously, such as reminders and alarms, in the latest version of Windows 10.

To update your version of Windows, select the Start button > Settings > Update & Security > Windows Update, and then select Check for updates.
If a feature update is available for your device, it will appear separately on the Windows Update page. To install it, select Download and install now.
