Enlarge / Cortana is gradually fading from Windows and other Microsoft products. (credit: Andrew Cunningham) Microsoft is working to cram its new ChatGPT-powered Bing Chat service into every product it makes, and starting this fall it will be a built-in feature of Windows 11. It makes sense, then, that Microsoft is also working to shut down its last stab at an automated virtual assistant—the standalone Cortana app in Windows 10 and Windows 11 is going to stop working this month, and Microsoft is pointing users toward Bing Chat and Windows Copilot instead. Some users have reported that the Cortana app has already stopped working entirely following an app update.
