As anticipated, Microsoft’s Cortana digital assistant will make the jump from Windows Phone to Windows 10, assuming control of many of the operating system’s search features. Cortana, which will get her own place next to the Start button in the desktop taskbar, can perform many of the same basic tricks she does in Windows Phone. Cortana can be interacted with via text or natural voice queries, just like on mobile devices.

Still based off Microsoft’s cloud-based Bing brains, Cortana can answer basic queries like “Will I need a coat tomorrow?” or how much it costs to attend the University of Washington, as Belfiore showed in live demonstrations. But Cortana’s also been tweaked for more useful PC-like interactions. She can scour your local machine, OneDrive account, and even your business network to find files based on natural language queries. Belfiore showed off the capabilities by asking Cortana to “Find PowerPoint slides about the charity auction” and “Show me photos from December.” The digital assistant surfaced the desired information nearly instantly.

That sounds pretty darn handy, and there are more playful commands, too: Telling Cortana to “Play my music” launches the music app, while asking her to “Please be quiet” silences the music. Nice!
