Preview builds for Windows 10 Redstone 5 (the update due to land later this year) are starting to come through more regularly now, and another one has just been released by Microsoft to ‘skip ahead’ testers and those on the fast ring.

Build 17682 features more work on Sets, which brings the concept of tabs from the web browser to the broader Windows 10 UI. Microsoft has made it so that when you click the ‘plus’ icon in a Sets window, apps are now more clearly highlighted, with applications included in your list of Frequent Destinations.
