What is the name of Windows 10's virtual desktop feature?

Windows 10's virtual desktop feature is called Task View. It provides an overview of open windows and lets users create and switch between multiple virtual desktops.

Task View was introduced with Windows 10 and can be opened from its taskbar button or with the Windows key plus Tab. Each virtual desktop can hold a different group of application windows, making it easier to separate work, communication, research, or entertainment. The feature changes the workspace arrangement without requiring multiple physical monitors.

Task View is also a task switcher, so its screen shows currently open windows even when virtual desktops are not being used. That makes it broader than a simple desktop selector. Snap Assist helps arrange windows, Aero Peek previews the desktop, and Flip 3D was an older window-switching interface associated with Windows Vista. Windows 11 kept Task View and added refinements such as separate wallpapers for individual virtual desktops.
