Windows Subsystem for Linux
Windows Subsystem for Linux (WSL) is a component of Microsoft Windows that allows the use of a Linux environment from within Windows, forgoing the overhead of a virtual machine and being an alternative to dual booting. The WSL command-line interface tool is installed by default in Windows 11, but a distribution must be downloaded and installed through it before use.
