Getting Started with Windows Subsystem for Linux Kernel 2: Installation and SetupThe Windows Subsystem for Linux (WSL) has revolutionized the way developers and system administrators work on Windows by allowing them to run a Linux environment directly on their Windows machines. With the introduction of WSL 2, Microsoft has significantly improved performance and compatibility by using a real Linux kernel. This article will guide you through the installation and setup of WSL 2, ensuring you can leverage the full power of Linux on your Windows system.
What is WSL 2?
WSL 2 is the second iteration of the Windows Subsystem for Linux, which provides a lightweight environment for running Linux distributions on Windows. Unlike WSL 1, which translated Linux system calls into Windows system calls, WSL 2 uses a full Linux kernel running in a lightweight virtual machine. This change enhances performance, compatibility, and the ability to run more complex applications.
System Requirements
Before you begin the installation, ensure your system meets the following requirements:
- Windows 10 Version 1903 or higher (Build 18362 or higher) or Windows 11.
- Virtualization must be enabled in your BIOS/UEFI settings.
- At least 4 GB of RAM is recommended for optimal performance.
Step-by-Step Installation Guide
Step 1: Enable WSL
-
Open PowerShell as Administrator:
- Right-click on the Start menu and select Windows PowerShell (Admin).
-
Run the following command to enable the WSL feature:
wsl --install
This command will enable the necessary components for WSL, including the Virtual Machine Platform and the Windows Subsystem for Linux.
- Restart your computer when prompted.
Step 2: Set WSL 2 as the Default Version
After your system restarts, you need to set WSL 2 as the default version:
-
Open PowerShell as Administrator again.
-
Run the following command:
wsl --set-default-version 2
This command ensures that any new Linux distributions you install will use WSL 2 by default.
Step 3: Install a Linux Distribution
You can install various Linux distributions from the Microsoft Store. Here’s how:
-
Open the Microsoft Store from the Start menu.
-
Search for “Linux” or the specific distribution you want (e.g., Ubuntu, Debian, Kali Linux).
-
Select your preferred distribution and click Install.
-
Once the installation is complete, you can launch the distribution from the Start menu.
Step 4: Initial Setup of the Linux Distribution
-
Launch the installed Linux distribution from the Start menu.
-
The first time you run it, you will be prompted to create a new user account and password. Follow the on-screen instructions to complete this setup.
-
After the setup, you will have access to a fully functional Linux terminal.
Configuring WSL 2
Accessing the Linux File System
You can access your Linux files from Windows by navigating to the following path in File Explorer:
\wsl$ This allows you to interact with your Linux files directly from Windows.
Updating and Upgrading Your Linux Distribution
To ensure your Linux environment is up to date, run the following commands in your Linux terminal:
sudo apt update sudo apt upgrade Installing Additional Software
You can install software using the package manager specific to your distribution. For example, on Ubuntu, you can use:
sudo apt install <package-name> Tips for Using WSL 2
- Accessing Windows Files: You can access your Windows files from within WSL by navigating to
/mnt/c/for the C: drive. - Using GUI Applications: WSL 2 supports running GUI applications natively. You can install and run applications like GIMP or Visual Studio Code directly from your Linux environment.
- Integrating with Visual Studio Code: You can use the Remote – WSL extension in Visual Studio Code to develop directly in your WSL environment.
Troubleshooting Common Issues
- WSL Not Starting: Ensure that virtualization is enabled in your BIOS/UEFI settings.
- Error Messages: If you encounter errors during installation, try running the commands in PowerShell as an administrator.
- Performance Issues: Ensure that your system meets the recommended hardware specifications for optimal performance.
Conclusion
With WSL 2, you can enjoy the best of both worlds: the powerful tools and applications available in Linux while working within the familiar Windows environment. By following this guide, you should now have WSL 2 installed and configured, ready for development and exploration. Whether you’re a developer
