Windows Subsystem for Linux (WSL) is a compatibility layer for running native Linux binaries on Windows. It allows developers to run a GNU/Linux environment - including most command-line tools, utilities, and applications directly on the Windows operating system.
Over a year ago, WSL was brought into Microsoft Store as a preview state for Windows 11 users. And now, the company has made it generally available for both Windows 10 and Windows 11 users.
