Microsoft has released a new sandbox that's built into Windows 10 Pro and Enterprise versions and allows people to run suspicious or untrusted files without needing a virtual machine. The Windows Sandbox gives enterprise users a simple integrated tool for executing and inspecting files that could be problematic. Each time a user starts that Windows Sandbox, it creates a clean, new image of Windows and once the user closes the sandbox, that image and all of the files associated with it are deleted. There are no traces left behind. �At its core Windows Sandbox is a lightweight virtual machine, so it needs an operating system image to boot from. One of the key enhancements we have made for Windows Sandbox is the ability to use a copy of the Windows 10 installed on your computer, instead of downloading a new VHD image as you would have to do with an ordinary virtual machine,� Hari Pulapaka, a group program manager for the Windows kernel at Microsoft said in a post.
