On Windows 10, Sets is a feature designed to group apps and websites into tabs to better organize your work, which works exactly the same as group tabs in your web browser.
However, if you have a particular app that you don’t want to use with groups of tabs, instead of disabling Sets on Windows 10, you can add the app to the list that you want to disable. For instance, perhaps you find Sets useful to group apps you frequently use, but you don’t want File Explorer, Settings, and Microsoft Store apps from being included into sets of tabs.
How to prevent apps from using Sets
If you want to prevent certain apps from being included in sets of tabs, then use these steps:
Click on System.
Click on Multitasking.
Under “Sets,” click on Add an app button.
Select the app you don’t want use with Sets.
Click on the OK button.
Once you’ve completed the steps, you can repeat the above instructions to add more apps to the list of apps that can’t be included in sets of tabs.
If you don’t see these settings, it’s because you’re not running a supported version of Windows 10. Sets is a feature expected to arrive with Windows 10 version 1809, but this can always change, because Microsoft has said that Sets will release when the company feels is ready.
