Windows Sandbox is a new feature in Windows 10 to help users run untrusted applications in a virtual environment. The feature makes it possible to safely run unknown (any application for that matter) in isolation.
A program running in Windows Sandbox cannot affect the host or Windows operating system and data in any way. When you close the Sandbox, Windows 10 automatically deletes the application and its data from your PC.
Windows Sandbox is like running another copy of Windows 10 on a virtual machine on your Windows 10 computer. But the only difference is that the feature built-in to Windows 10 and changes are not saved when you exit the Sandbox.
However, the feature is currently available in Pro and Enterprise editions of Windows 10 only. This means that PC users running Windows 10 Home edition will have to use third-party sandbox software like Sandboxie to get the sandbox environment.
With default settings, Windows Sandbox feature is turned off. If you wish to enable the feature or would like to disable the same after using it for a while, you can do so under Windows Features.

The Windows Sandbox feature is not yet a released feature of Windows 10. It is only available in the “Insider Preview” version (build 18305), which is planned for release in first half of 2019. If you are not signed up for Windows Insider Previews you will not find this feature in the “Windows Features” choices.
