For those who have no idea about Windows Sandbox, it is a small integrated desktop environment that allows you to safely run applications in an isolated environment.

What is Windows Sandbox?

Windows Sandbox provides an easy working environment for secure and isolated application operation. Software installed in a Windows Sandbox environment remains a “sandbox” and runs separately from the main computer.

The sandbox is temporary. When it is closed, all software, files, and reports are deleted. Each time you open an application, you get a brand new instance of the sandbox.

Windows Sandbox is designed to run an untrusted application in an isolated environment such as a virtual machine. It is a lightweight virtual machine, an ideal tool often used by developers. If you haven’t heard of Windows Sandbox, find it here and install it. Installing Windows Sandbox is very easy, but in my experience, it is a bit tricky. After installing Windows Sandbox, many users may encounter this error.

Software and applications installed on the host are not directly available in the Sandbox. If you need certain applications in a Windows Sandbox environment, they must be explicitly installed in that environment.

Windows Sandbox has the following features :

  • Part of Windows: everything you need for this feature is included in Windows 10 Pro and Enterprise. There is no need to load a VHD.
  • Pristine: Every time the Windows Sandbox is started, it is as clean as a brand new Windows installation.
  • Disposable: Nothing is left on the device. Everything is discarded when the user closes the application.
  • Security: Uses hardware virtualization to isolate the kernel. It relies on the Microsoft hypervisor to run a separate kernel which isolates the Windows sandbox from the host.
  • Efficient: Uses a built-in kernel scheduler, intelligent memory management, and virtual GPU.
