Microsoft showed off a small number of Windows 10 features at the company’s event on Tuesday morning, but one rumored one was missing: Cortana. The software maker focused on some of its desktop improvements for Windows 10, and Cortana is one of the many changes that will be coming ahead of the final release next year. While the special Technical Preview build of Windows 10 that will be released tomorrow won’t include Cortana, Microsoft is already testing the digital assistant inside of other Windows 10 builds internally. It’s an early implementation, but Cortana will be fully integrated into the search experience in Windows 10. Microsoft’s new Windows 10 OS has a new search button on the taskbar, and Cortana currently appears at the top of that search functionality once it’s triggered. Just like Windows Phone, you can type to Cortana to ask it to remind you to do things, or to search for content locally in apps or on the web.
