Uninstall WSL: Step-by-Step Simple Guide

uninstall wsl blog

how to uninstall wsl blog

A lot of people want Linux but do not want to go either remove Windows or take up the overwhelming task of dual booting. For those people, WSL (Windows Subsystem for Linux) came as a blessing. WSL lets you run Linux on your Windows device without the overhead of a Virtual Machine (VM). But in some cases where you want to fix a problem or simply do not want WSL anymore, you may have to uninstall WSL from your Windows system.

Here is step-by-step guide to remove WSL from your Windows system, remove any Linux distribution, delete all related files, and clear up some disk space. Ready? Get. Set. Learn!

What is WSL

You probably knew by now that we will always start with the basics i.e., what WSL does. Think of WSL as a compatibility layer for running Linux binaries on Microsoft Windows systems. It comes in two versions:

  • WSL 1: Uses a translation layer between Linux and Windows.
  • WSL 2: Uses a real Linux kernel in a lightweight VM.

All around the world, WSL is a favourite among developers, system administrators, and students for running Linux tools like bash, ssh, grep, awk, and even Docker. But if you have moved to a proper Linux system or just want to do a clean reinstall, here are the instructions to remove WSL completely without any errors.

Step 1: How to Uninstall Linux Distributions

The first step to uninstall WSL completely is to remove all installed Linux distributions.

Check Installed Distros

To check for the installed Linux distributions, open PowerShell or Command Prompt and run the command:

wsl --list --all

After executing this command, you will see a list of installed distros, such as:

  • Ubuntu
  • Debian
  • Kali
  • Alpine

How to Uninstall a Linux Distro

To uninstall a distro like Ubuntu, follow these instructions:

  1. Press Windows key + I to open Settings window.
  2. Go to Apps, then click Installed Apps (or Apps & Features).
  3. Search for your distro and click Uninstall.

Repeat for all distros you no longer need. If you plan to uninstall WSL completely, we recommend removing all distros.

if you prefer PowerShell, run these commands

wsl --unregister <DistroName>

For example, if you want to remove Ubuntu, execute the command:

wsl --unregister Ubuntu

This removes the Linux distro and all its associated files.

Step 2: Uninstall WSL Components

Once we have removed the unwanted distros, let us uninstall the WSL platform itself.

  1. Open Control Panel and navigate to Programs and then click Turn Windows features on or off.
  2. Uncheck these boxes:
    1. Windows Subsystem for Linux
    2. Virtual Machine Platform (used by WSL 2)
    3. Windows Hypervisor Platform (optional)
  3. Click OK and restart your system.

Step 3: Remove WSL Files and Cache

Even after uninstalling WSL and Linux distributions, some data might remain. Here are the instructions to delete WSL’s cached files and reclaim disk space.

To delete the WSL Folder, open File Explorer and go to:

%USERPROFILE%\AppData\Local\Packages

Look for folders like:

  • CanonicalGroupLimited…Ubuntu
  • Debian…
  • KaliLinux…

Delete any folders related to WSL distros you removed.

Step 4: Remove WSL CLI Tool (Optional)

If you installed WSL using the Microsoft Store (i.e., “wsl.exe” package), you can also uninstall it directly from the Installed Apps section:

  1. Go to Settings, and then to Apps and then open Installed Apps.
  2. Search for Windows Subsystem for Linux.
  3. Click Uninstall.

Step 5: Clean Up with Disk Cleanup Tool

Finally, use the built-in Disk Cleanup utility to clear any temporary files.

  1. Press “Windows key + S and search for Disk Cleanup.
  2. Choose your system drive (usually drive C:).
  3. Select options like:
    1. Temporary files
    2. System created Windows error reporting
    3. Delivery optimization files
  4. Click OK to clean up.

Bonus Section: How to Reinstall WSL (Optional)

If you are removing WSL due to issues or conflicts, you can always do a fresh reinstall.

Here is how you can install latest version of WSL via PowerShell

wsl --install

This installs WSL 2 by default, along with Ubuntu.

Wrapping Up

Uninstalling WSL may sound tricky, but by following these steps, you can completely remove Linux distributions, WSL components, and unwanted files from your system. Whether you are making space for something new or just doing some digital spring cleaning, this guide ensures that WSL is uninstalled safely and cleanly.

If you ever want to come back to the Linux world, WSL can be reinstalled with a single command, which we have covered as a precaution. Let us know if you face any errors. Happy learning!

shopt in Bash: How to Improve Script Reliability

shopt blog

shopt tutorial blog banner image

There are multiple very useful built-ins in Bash other than cd, ls, and echo. For shell scripting and terminal command execution, there is one lesser known but very powerful built-in command. It is the ” shopt”. This comes in handy when you are customizing your shell behaviour or writing advanced scripts. If you understand shopt, you can improve your workflow and also your scripts’ reliability.

In this guide, let us explain everything there is about the shopt command, how to use it, and some practical applications as well (as usual in Unixmen). Ready? Get. Set. Learn!

The Basics: What is shopt

shopt stands for Shell Options. It is a built-in command in Bash, that allows you to view and modify the behaviour of the shell by enabling or disabling certain options. These options affect things like filename expansion, command history behaviour, script execution, and more.

Unlike environment variables, options in shopt are either on or off i.e., boolean.

Basic Syntax of shopt

Here is the basic syntax of shopt command:

shopt [options] [optname...]

Executing

  • Without arguments: Lists all shell options and their current status (on or off).
  • With “-s” (set): Turns on the specified option.
  • With “-u” (unset): Turns off the specified option.
  • Use “-q” (quiet): Suppresses output, useful in scripts for conditional checks.

How to View All Available Shell Options

To view the list of all shopt options and to see which are enabled, execute this command:

shopt

The output to this command will list the options and their status like:

autocd on
cdable_vars off
dotglob off
extglob on

Enabling and Disabling Options with shopt

We just learnt how to see if an option is enabled or not. Now let us learn how to enable an option:

shopt -s optname

Similarly, execute this command to disable an option:

shopt -u optname

Here is a couple of examples:

shopt -s dotglob # This command is to include dotfiles in pathname expansion
shopt -u dotglob # This command is to exclude dotfiles (which is the default behaviour)

Some of the Commonly Used shopt Options

Here are some shopt options that will be useful for you:

dotglob

When this option is enabled, shell includes dotfiles in globbing patterns i.e., the * operator will match “.bashrc”. This option will be helpful for you when you want to apply operations to hidden files.

shopt -s dotglob

autocd

The autocd option lets you cd into a directory without typing the cd command explicitly. For example, typing “Documents” will change into the “Documents” directory. Here is how you can enable it:

shopt -s autocd

nocaseglob

This option makes filename matching case insensitive. Using this option will help you when you write scripts that deal with unpredictable casing in filenames.

shopt -s nocaseglob

How to Write Scripts with shopt

You can use shopt within Bash scripts to ensure consistent behaviour, especially for scripts that involve operations like pattern matching and history control. Here is an example script snippet to get you started:

# First let us enable dotglob to include dotfiles
shopt -s dotglob

for file in *; do
echo "Processing $file"
done

In this script, “dotglob” option ensures hidden files are also processed by the “for” loop.

Resetting All shopt Options

If you’ve made changes and want to restore to the default behaviours, you can unset the options you enabled by executing these commands for the appropriate options:

shopt -u dotglob
shopt -u autocd
shopt -u extglob

Advantages of shopt

It gives you fine-grained control over your shell environment. Once you are familiar with it, it improves script portability and reliability. With shopt, you can enable advanced pattern matching and globbing. It can be toggled temporarily and reset as needed and also helps you avoid unexpected behaviours when writing automation scripts.

Wrapping Up

The shopt command is not as famous as other built-in tools in shell but it a very powerful hidden gem. Whether you are starting to explore shell scripting or you are a power user automating workflows, learning to use shopt can save time and prevent headaches. Once you’re comfortable, you’ll find that Bash scripting becomes more predictable and powerful.

Understanding DNS: What’s My DNS and Why Does It Matter?

In today’s interconnected world, DNS plays a crucial role in how we access websites and online services. If you’ve ever wondered “what’s my DNS?” or why it matters, this comprehensive guide will explain everything you need to know about DNS settings, how to check them, and why they’re important for your online experience.

What is DNS?

DNS (Domain Name System) acts as the internet’s phonebook, translating human-friendly website names like “example.com” into machine-readable IP addresses that computers use to identify each other. Without DNS, you’d need to remember complex numerical addresses instead of simple domain names.

Why Should You Know Your DNS Settings?

Understanding your DNS configuration offers several benefits:

  • Improved browsing speed: Some DNS providers offer faster resolution times than others
  • Enhanced security: Certain DNS services include protection against malicious websites
  • Access to blocked content: Alternative DNS servers can sometimes bypass regional restrictions
  • Troubleshooting: Knowing your DNS settings is essential when diagnosing connection issues

How to Check “What’s My DNS” on Different Devices

Linux

  1. Open Terminal
  2. Type
    cat /etc/resolv.conf

    and press Enter

  3. Look for “nameserver” entries

Windows

  1. Open Command Prompt (search for “cmd” in the Start menu)
  2. Type
    ipconfig /all

    and press Enter

  3. Look for “DNS Servers” in the results

Mac

Popular DNS Providers

Several organizations offer public DNS services with various features:

  • Google DNS: 8.8.8.8 and 8.8.4.4
  • Cloudflare: 1.1.1.1 and 1.0.0.1
  • OpenDNS: 208.67.222.222 and 208.67.220.220
  • Quad9: 9.9.9.9 and 149.112.112.112

When to Consider Changing Your DNS

You might want to change your default DNS settings if:

  • You experience slow website loading times
  • You want additional security features
  • Your current DNS service is unreliable
  • You’re looking to bypass certain network restrictions

The Impact of DNS on Security and Privacy

Your DNS provider can see which websites you visit, making your choice of DNS service an important privacy consideration. Some providers offer enhanced privacy features like DNS-over-HTTPS (DoH) or DNS-over-TLS (DoT) to encrypt your DNS queries.

Summary

Knowing “what’s my DNS” is more than just technical curiosity—it’s an important aspect of managing your internet connection effectively. Whether you’re troubleshooting connection issues, looking to improve performance, or concerned about privacy, understanding and potentially customizing your DNS settings can significantly enhance your online experience.
