Introducing Sets

One of the biggest digital challenges today is pulling together that ideal mix of apps and websites to complete everything from writing a report for work to planning a weekend getaway. Finding time to work on these things often falls into an unpredictable schedule that gets interrupted by other commitments. Oftentimes, there is nothing more frustrating than pulling up files, websites, notes, and apps, only to be pulled away to something else. It can be like a never-ending game of musical chairs.

This Windows 10 Insider Preview Build will hopefully set the stage as we try to make starting, stopping, and continuing complex tasks a painless activity with a new feature called Sets.

The basics

Sets: With all the elements that go into a task, sometimes convincing yourself to get started is the hardest part. Sets help you keep webpages, documents, files, and apps connected, while remaining just one click away. When you close a file that includes a group of tabs, we’ll help you bring those tabs back to life the next time you open it. Whether it’s something you pick up later in the day or in a couple weeks, Sets is being designed to help you keep the important things together.

Add tabs to apps: To help fuel Sets, most apps will be able to add app and web tabs. When you select a link in something like an email, it’ll open in a new tab next to the app you were using. Selecting the plus (+) in an app will take you to a new tab page, which will help you jump to your next location. You might already know where you want to go, or just need a little bit of inspiration. From here, you’ll be able to search your PC and the internet, access customized feeds, open frequently used websites and apps, and get suggestions based on your recent activity.

How you can help

This is new territory for us, so we’re excited to get your feedback from the start. Your input will play a key role in how we’ll craft this experience and we’re looking forward to seeing where this collaboration takes us.

Let us know any opinions and suggestions about Sets that you can dream up. One of the best ways to contribute is using Quests found in the Feedback Hub. Remember that this is a controlled study, so not all Windows Insiders will see Sets.

More info on this approach can be found in our flight blog posts.

What you’ll see in the December release

  • Modern apps can add web tabs.
  • Sets of tabs will automatically save with most files and will automatically restore the next time you open them.
  • App tabs can be dragged out of a Set.
  • The new tab page will allow you to search the web, access frequently visited websites, and browse a newsfeed.

What we’re targeting for future releases

  • Desktop apps and File Explorer will be able to add tabs.
  • Tabs can be merged together.
  • Web tabs can be dragged out of a Set.
  • You will be able to control which tabs you restore when launching a Set.
  • Timeline integration.
  • The new tab page will allow local search, show frequently visited apps, and include additional feeds.
  • The new tab page will be able to launch apps in a new tab.


We created some keyboard shortcuts for Sets. Some might be challenging, so we welcome your feedback.

Shortcuts Action
Win+Ctrl+Tab Switch to the next tab
Win+Ctrl+Shift+Tab Switch to the previous tab
Win+Ctrl+W Close the active tab
Win+Ctrl+1 through 8 Switch to a specific tab
Win+Ctrl+9 Switch to the last tab
Win+Ctrl+T Open a new tab

Throughout this process, we’ve put a lot of effort into making Sets easy to use for everyone. We expect to have Narrator support soon, and screen-reader functionality is also on the horizon.

If you’re currently using Ease of Access tools and don’t want this experience, you can turn it off in Settings > System > Multitasking > Uncheck Tabs in apps.
