Microsoft has released an Insider Preview Build that includes the new Windows Sandbox feature. If you’re on the Fast track, you can download and start using it today.

Note: Windows Sandbox is not available on Windows 10 Home. It’s only available on Professional, Enterprise, and Education editions of Windows 10.

#What is Sandbox?

In short, Windows Sandbox is half app, half virtual machine. It lets you quickly spin up a virtual clean OS imaged from your system’s current state so that you can test programs or files in a secure environment that’s isolated from your main system. When you close the sandbox, it destroys that state. Nothing can get from the sandbox to your main installation of Windows, and nothing remains after closing it.
