Today Microsoft released Windows 10 Insider Preview Build 17682 (Redstone 5) to insiders in the fast and skip ahead rings. This build introduces improvements to Sets, updates to the wireless projection experience, Microsoft Edge improvements, adds RSAT to the optional features, and displays a new post-upgrade screen showing various features that can be setup.

As many people did not realize you can use the new tab page, + (plus) tab, in Sets to launch applications, this build will cause the new tab page to list common apps under "Frequent destinations" and also allow you to explore all applications.
