Sets is a tabbing system that will work across Windows 10. Essentially a universal tab ability for applications. It works like tabs on a web browser, allowing users to open a tab in an application by clicking a + symbol in the title bar. A new tab will show recent apps, documents, and a search. The concept of using Windows 10 Sets is to be able to multi-task more easily without needing to leave an app you are in. However, Sets has been delayed numerous times after its initial slated April 2018 launch. After another delay again last year, Microsoft revealed in April Sets was taken off the development cycle and effectively cancelled. Hopes were raised when a rumor suggested Windows 10 Insider Preview Build 19481 would include a rejuvenated Sets.

Future
Microsoft has shot down those hopes, although it seems Sets will eventually return. Brandon LeBlanc, Senior Program Manager for Microsoft, was asked if Set would return in Build 19481. LeBlanc’s response was to the point, “Nope”. That said, LeBlanc did not say Sets would never come back, but it may not be called Sets. Senior PM Rich Turner previously discussed Microsoft’s decision to pause development on the tool. He said the “Shell-provided tab experience is no more”. Despite the seeming end of the feature, Turner said Microsoft is still committed to adding a tab experience to Windows 10.
