If you want to spin up an isolated Windows 10 desktop quickly, without the knowledge required to work with virtual machines (VM) or the cloud, then Windows Sandbox is the answer. How does Windows Sandbox work? Windows Sandbox is a feature in Windows 10 Pro, Enterprise, and Education SKUs, which provides users an easy way to quickly test apps in isolation. It uses a clean operating system image that is generated from your system’s current state, so there’s no need to download and install Windows.
