Restart WSL: A Step-by-Step Guide to Refresh Your Windows Subsystem for Linux

Restarting Windows Subsystem for Linux (WSL) is a straightforward process. Whether you’re experiencing issues with your current instance or just need to refresh the system, a quick restart can do the trick. In less than a minute, you can have WSL up and running again.

Step by Step Tutorial on How to Restart WSL

Before we dive into the steps, it’s important to know that restarting WSL effectively closes all running Linux applications and resets the system. This can be helpful if you’re dealing with unresponsive programs or system errors.

Step 1: Open Command Prompt or PowerShell

Open either Command Prompt or PowerShell as an administrator.

The Command Prompt or PowerShell can be found by searching for them in the start menu. Make sure to right-click and select "Run as administrator" for the necessary permissions to restart WSL.

Step 2: Enter the Restart Command

Type wsl --shutdown and then press Enter.

This command will immediately shut down all running instances of WSL. It’s a simple but powerful command that effectively resets the subsystem.

Step 3: Restart WSL

Open your preferred Linux distribution to restart WSL.

After shutting down WSL, you can start it back up by simply opening your Linux distribution of choice from the start menu. This will boot up WSL as if you’re starting it for the first time.

After completing these steps, WSL will restart and you’ll be back in a fresh session. Any temporary system errors or issues should be resolved, and you can continue working on your Linux projects without interruption.

Tips for Restarting WSL

  • Always save your work before restarting WSL, as unsaved changes will be lost.
  • If you’re experiencing persistent issues with WSL, consider checking for updates or reinstalling the distribution.
  • Use wsl --list --running to check if any distributions are currently running before you restart.
  • Keep in mind that restarting WSL does not affect your Windows system or files.
  • If you have multiple WSL distributions installed, you can restart them individually by specifying the distribution name with the wsl --shutdown [distribution] command.
