A new preview build for Windows 10 has been released to allow quick call testers to test the 20H1 update; in other words, the update that will be released in the first half of next year. It greatly improves the search experience in File Explorer. File explorer is the application you use to explore files and folders on the desktop. In the state, a search done in a folder window (using the top right frame with the little magnifying glass icon) is a pretty basic affair compared to the full Windows search experience. So the idea is to bring this last full experience, i.e. the search functionality you get when searching for objects via the search/Cortana box next to the Home button in the browser. files, so when you type a search query, you'll get a drop-down list of suggested files to search for. If you see the file you need after typing just a few letters, just click it to open it (or right-click if you just want to navigate to the file's location). Microsoft also explains that this change will also integrate your files stored online on OneDrive into search results. The general idea is to make search more consistent (and useful) every time you use it on Windows, which can't be a bad thing. That being said, the feature is still in its infancy and has only been implemented by a "small percentage" of testers at this point. We can imagine that it will be available to more Windows folks trying out the 20H1 update before too long, but you may not see it for a while.
