Having Cortana introduce herself was a welcome as well as horror for Windows 10 users, setting up their devices. But with the latest Insider Build 18309, things have changed. Microsoft has silenced Cortana by default on the Pro, Enterprise, or Education editions of Windows. (via Windows Central)
Here’s what the Build’s changelog notes –
Based on feedback, if you clean install Pro, Enterprise, or Education editions of Windows, the Cortana voice-over will be disabled by default. Screen reader users can still choose to start Narrator at any time by pressing WIN + Ctrl + Enter.
However, for those using Windows 10 Home, you can still enjoy the takeover of Cortana during setup. Enjoy this video of many PCs reciting the same Cortana phrases.
