Create a virtual desktop

[tasnuba.swe]

In the taskbar of Windows 10 you’ll see a new icon to the right of the search bar which looks like a rectangle with two smaller ones slightly behind it. This is called Task View, and clicking it will give you a thumbnail view of all the programs which are running. The same thing can be achieved by using the key combination of Win+Tab. When in Task View mode you’ll see an option in the bottom right corner that has a large Plus sign with New Desktop written below. Clicking on this will create a new desktop, one that looks and behaves identically to your normal one, but has no apps running on it.
