In the Windows 10 Technical Preview, you can add a seemingly unlimited number of virtual desktops quickly and easily, thanks to the new Task View pane. Unfortunately, Windows 10’s multiple desktop functionality is still very limited — you can’t drag and drop programs between different screens, you can’t change the wallpaper for individual desktops, and you can’t quickly jump to a particular screen without cycling through all of your open screens.
Step 1: Add a desktop
Step 2: Switch between desktops
Step 3: Move windows between desktops
Step 4: Close a desktop
To close a virtual desktop, open up the Task View pane and hover over the desktop you want to close until a small X appears in the upper right corner. Click the X to close the desktop. You can also close desktops without going into the Task View pane by using the keyboard shortcut Windows Key + Ctrl + F4 (this will close the desktop you’re currently on).
