Windows Sandbox — light weight playground for R&D, tutorials and workshops

Windows Sandbox to me is a light weight Windows 10 virtual machine that I can quickly start and stop and use to install and run programs. The Windows Sandbox provides a well defined, clean environment that is fresh every time it is started. Inside the Sandbox, I can create an isolated environment for working through a tutorial or the labs in a workshop or for doing R&D to stuff I do not want (yet) in my regular Windows environment. One instance of the Sandbox can run at any one time.
