The Windows Subsystem for Linux (WSL) allows Linux applications to run natively on Windows 10 and 11.It offers two versions: WSL 1, which translates Linux system calls to Windows calls, and WSL 2, which uses a real Linux kernel.To install WSL from PowerShell, open PowerShell as Administrator and run the command 'wsl --install'. Restart your PC when prompted.After installation, configure the Linux environment and install applications like Git, Node.js, Python, and Docker.
