What is the virtual desktop software that comes with Windows 10 and 11 called?

Although Hyper-V is a part of Windows, it is disabled by default in Windows 10, Windows 11, Pro, and higher editions. Open Control Panel, choose Programs and Features, and then click Turn Windows features on or off to enable it. Look for Hyper-V (Windows 11) or Windows Hypervisor Platform (Windows 10) in the dialog box that appears, choose it by checking the box next to the option, and then click OK. Microsoft's cloud-based desktop is called Azure Virtual Desktop, while VirtualBox is freeware from Oracle and VMware Fusion is virtual machine software for macOS.
