One of the more interesting features of Windows 10 version 1903, otherwise known as the May 2019 Update, is the Windows Sandbox. The Windows Sandbox is a Windows 10 virtual machine that can be quickly launched so you can test downloaded programs,browsers extensions, and suspect sites without risk of infecting your normal Windows operating system.

For those who are security conscious and do not want to deal with installing a dedicated virtual machine program like VirtualBox, Hyper-V, or VMWare, you can instead install Windows Sandbox for a very basic Windows 10 virtual machine.
