About Wsl

Windows Subsystem for Linux (WSL) is an open source Microsoft tool that lets users run unmodified Linux command-line tools, utilities, and applications directly on the Windows operating system. It removes the need for traditional virtual machine setups or dual boot configurations, reducing overhead for users who need access to Linux software.

You can install WSL quickly by running the wsl --install command in the Windows command line. The project is supported by related open source repositories, including one for the custom Linux kernel shipped with WSL and another for Linux GUI app support. The software logs basic diagnostic telemetry by default, which users can disable per the repository’s documentation.

WSL is designed for Windows users who regularly need Linux tooling for tasks like software development, scripting, or system administration, without switching their primary operating system.
