Unlike a full VM, it uses HyperV under the hood but shares the host OS files and memory pages, keeping its footprint to around 500MB disk and 4GB RAM by default. When closed, all state is wiped. It can be enabled via Windows Features and customized through an XML config file (.wsb extension) to disable networking, map read-only host folders, adjust memory, and add extra app isolation. A command-line interface is also available for scripting interactions. ## Full article daily.dev links to this article rather than hosting it.
