Microsoft recently started rolling out Windows 10 Insider Preview Build 17618 for Windows 10 Insiders who have opted into Skip Ahead. The latest build reintroduces the ‘Sets’ feature which first debuted last year but didn’t make the cut for the RS4 update.

The Windows Experience Blog announcing the release also lists a few handy keyboard shortcuts users can try out while testing Sets:

The blog post also highlights additional features for Sets that the company is currently working on:

  • Tab drag-and-drop does not work for re-ordering tabs. Users can’t drag a tab to join another window.
  • When launching a supported desktop (Win32) app from a tabbed window, it launched a new window instead of auto-grouping to the existing window.
  • Users might notice some flashes while switching between tabs within a Set.
  • If the display scaling is higher than 100%, using touch to interact with the Sets title bar won’t work.

The company is working to fix the aforementioned issues and is expected to release them in subsequent RS5 updates. Users also have the ability to enable or disable Sets from Setting>System>Multitasking.
