https://arstechnica.com/gadgets/2019/01/next-windows-10-version-will-let-you-search-without-cortanas-involvement/ > Today's Insider build of Windows 10, number 18317, changes how search and Cortana are used, as Microsoft is working to reposition Cortana as a productivity-focused digital assistant and integrate search with Office 365. > Currently, Windows 10 has a single text box on the taskbar that's used for searches and Cortana commands. Type a word or two and it'll search the Start menu, settings, and documents. But type a command ("tell me a joke," say) and no search is performed; instead, the command is delivered to Cortana, and she duly responds. In the new build, the text box is used solely for searching. To give Cortana a command, you'll have to speak to her or click a separate Cortana button on the taskbar.
