Microsoft replaces the old Task View button with a redesigned icon on the taskbar, which makes it easier to create and manage multiple desktops. Just hover over the icon to see any open virtual desktops or create a new desktop. You can then rearrange these desktops as necessary and drag apps from one desktop to another.

You can use different wallpapers for each virtual desktop to better differentiate them. Right-click on the desktop, choose Personalize > Background, and then pick a distinct image. Note that this works only for the Background choice, not for Themes. If you choose a Theme, it applies to all virtual desktops. After applying a theme, however, you can change the background of each desktop. If you do, you see a cool cross-fade effect between the two backgrounds when you switch between them.
