How did an operating system that routinely catches flak from hardcore open-source purists become the de facto standard for so much of the computing world? As a recent retrospective by Zunaid Ali at How-To Geek points out, Ubuntu did not conquer the Linux landscape by winning every technical benchmark or satisfying every hobbyist's customization itch. Instead, Canonical—the company behind Ubuntu—built an empire on frictionless distribution, institutional inertia, and the compounding power of being the default choice when organizations, educators, and software vendors make the call.
For Windows administrators, developers, and PC power users, understanding how Ubuntu achieved that position—and where it actually leads versus where it trails—explains why it shows up automatically in modern Microsoft workflows and how you can swap it out if your workload calls for something else.
Solving the Distribution Bottleneck with Free CDs
To understand how Ubuntu gained its initial foothold, you have to rewind to the broadband dark ages of 2004. Back then, curious Windows users who wanted to experiment with Linux faced an immediate logistical wall: downloading multi-hundred-megabyte ISO files over dial-up or early, metered DSL connections was a grueling exercise in patience.
When Mark Shuttleworth announced Ubuntu 4.10 ("Warty Warthog") on October 20, 2004, Canonical attacked that bottleneck directly. Alongside a commitment to 18 months of security updates and a single-CD installation, Canonical launched the ShipIt program. Anyone anywhere in the world could go online and request free, shrink-wrapped Ubuntu CDs delivered in the mail at no cost—not just a single disc for a home PC, but bundles of discs for friends, schools, or local Linux User Groups (LUGs).
Canonical positioned Ubuntu directly against Microsoft's desktop dominance. According to How-To Geek's reporting, two months prior to that initial 4.10 release, Shuttleworth filed "Bug #1" on Launchpad titled "Microsoft has a majority market share," framing free, accessible software as the remedy.
By the time Canonical officially wound down the direct ShipIt web request portal on April 5, 2011 (just ahead of Ubuntu 11.04), the company reported in an official blog post that it had shipped millions of physical CDs to every country in the world. Even after ending individual mail-order requests as broadband became widespread, Canonical continued supplying discs in bulk to Ubuntu Local Communities (LoCos) for events and explicitly encouraged users to copy and redistribute the media freely. By removing the physical barrier to entry during the mid-2000s, Ubuntu ensured that millions of first-time Linux users started in its ecosystem.
Key Takeaways: Early Growth
- Zero-Cost Physical Access: Canonical's ShipIt program (2004–2011) mailed millions of free installation CDs globally when internet speeds made ISO downloads impractical.
- Predictable Cadence: Six-month release cycles paired with guaranteed security update windows gave schools and early adopters a reliable schedule.
The Network Effect: Why Developers and Tutorials Assumed Ubuntu
Once a critical mass of newcomers landed on Ubuntu, a classic software network effect kicked in. Because new users were predominantly running Ubuntu, community writers, educators, and Q&A forums wrote their step-by-step guides using apt commands and Ubuntu file paths. Because the documentation and user base were concentrated on Ubuntu, third-party software vendors naturally targeted .deb packages and Ubuntu Long Term Support (LTS) releases first.
How-To Geek highlights PC gaming as a prime historical example of this snowball effect. When Valve originally brought the Steam client to Linux in February 2013, it launched through the Ubuntu Software Center and officially targeted Ubuntu 12.04 during its beta phase. If you wanted the path of least resistance for third-party applications, proprietary drivers, or developer toolchains in the early 2010s, installing Ubuntu meant you were standing right where the vendors were aiming.
Where "Popular" Depends on Who Is Choosing
Here is where the story gets nuanced—and where it pays to separate hobbyist enthusiasm from institutional deployment. Saying Ubuntu is "the most popular Linux distro" without qualification flattens out very different user populations. When individual enthusiasts and gamers hand-pick a distribution for their personal rigs today, Ubuntu often loses out to rolling-release or gaming-tuned alternatives. When organizations, cloud hosts, or development platforms set the standard, Ubuntu still dominates.
| Segment / Metric | Reported Standing | Primary Context & Caveats |
|---|---|---|
| Linux Gaming (Steam) | Trails CachyOS, SteamOS, and Arch Linux | How-To Geek cites the September 2026 Steam Hardware Survey showing CachyOS at 18.12%, SteamOS at 17.37%, Arch at 10.67%, and combined Ubuntu entries at roughly 8% of sampled Linux gamers. |
| Professional Developers | #1 Named Linux Distro (27.7%) | Citing Stack Overflow's 2024 Developer Survey, How-To Geek notes 27.7% of professional developers reported Ubuntu as their primary OS. |
| Enterprise Servers | #1 Most-Used Enterprise Distro | OpenLogic's 2025 State of Open Source report found Ubuntu led across company sizes and regions (except Asia, where CentOS led), and ranked as the top planned CentOS migration target outside Europe. |
| Windows Subsystem for Linux | Default Out-of-the-Box Distro | Microsoft's wsl --install command provisions Ubuntu automatically unless an administrator or user passes a distribution flag. |
The Enthusiast Desktop vs. The Enterprise Server
As reported by How-To Geek, Canonical's own priorities shifted noticeably in April 2017, when Shuttleworth ended Canonical's investment in the Unity8 desktop interface and Ubuntu phone hardware, returning Ubuntu 18.04 LTS to the GNOME desktop and focusing heavily on cloud and IoT workloads. How-To Geek also reports that according to Canonical's full accounts for the year ended December 31, 2025 (filed with UK Companies House in June 2026), company revenue rose 18% to $345 million, driven largely by recurring software and enterprise support subscriptions.
That enterprise focus paid off handsomely during the upheaval following the retirement of traditional CentOS. After the CentOS Project pivoted to CentOS Stream in December 2020 and CentOS Linux 7 reached its final end of life on June 30, 2024, IT departments had to find a stable new home for their server fleets.
According to OpenLogic's 2025 State of Open Source Report (published in mid-2025, roughly a year after CentOS 7 EOL), Ubuntu remained the most-used enterprise Linux distribution overall across company sizes and industry verticals—trailing only in the banking and finance sector (where Red Hat Enterprise Linux and CentOS led) and in Asia (where CentOS remained first and Ubuntu tied with Fedora for second). Furthermore, when OpenLogic surveyed organizations still running EOL CentOS servers about where they intended to migrate, Ubuntu was the number-one planned destination everywhere except Europe (where 27% of respondents answered "I don't know" compared to 18% selecting Ubuntu).
Of course, IT veterans know that a survey of planned migrations is not a census of completed server cutovers—OpenLogic noted that 40% of the largest enterprises surveyed were still running CentOS a year after EOL, and teams reported that real-world migrations were taking longer than expected. Even so, Ubuntu's five-year standard LTS support window and predictable release cadence made it an easy boardroom answer.
The Microsoft Connection: How WSL Keeps Ubuntu First in Line on Windows
Ironically, one of the biggest engines putting Ubuntu onto modern desktops today is Microsoft itself.
Back in 2004, Canonical treated Microsoft's market share as "Bug #1". Today, on Windows 10 (version 2004, Build 19041 and higher) and Windows 11, Microsoft's Windows Subsystem for Linux (WSL) lets developers and sysadmins run unmodified Linux binaries, Bash scripts, and command-line utilities directly alongside Windows applications without the overhead of a traditional virtual machine or a precarious dual-boot partition.
And what happens when a Windows user opens an elevated PowerShell prompt or Windows Terminal and runs Microsoft's standard single-command setup?
wsl --install
As documented in Microsoft Learn's official WSL command reference, running wsl --install without extra arguments enables the required Windows virtualization components and automatically downloads and installs Ubuntu as the default Linux distribution. Because millions of students, web developers, and Windows systems administrators follow Microsoft's quick-start documentation verbatim, Ubuntu wins by default before the user even considers another distribution.
Practical Guide: Choosing Your Own Distro in WSL
Ubuntu may be Microsoft's default out-of-the-box selection for WSL, but Windows users are by no means locked into it. Whether you prefer plain Debian, Kali Linux for security auditing, openSUSE, or Arch Linux, Microsoft builds distribution choice directly into wsl.exe.
Here is how you can inspect, install, and switch distributions on Windows 11 or Windows 10:
- See what distributions are available online:
Before installing, open PowerShell or Windows Command Prompt and query the online store list:
wsl --list --online
(You can also use the shorthandwsl -l -o.) - Install a specific distribution instead of Ubuntu:
Use the-d(or--distribution) flag during installation, replacing<DistributionName>with the exact name from the online list:
wsl --install -d <DistributionName>
(Note: If you want to install the WSL engine without installing any Linux distribution at all, Microsoft supports runningwsl --install --no-distribution.) - Check which distributions and WSL versions you currently have installed:
If you already have WSL running and want to see whether Ubuntu or another distro is active on WSL 1 or WSL 2, run:
wsl --list --verbose - Change your default WSL distribution:
If you install multiple Linux environments side by side in Windows Terminal and wantwslcommands to target a different distro by default, run:
wsl --set-default <DistributionName> - Remove a distribution you no longer need:
If you tested default Ubuntu (or another distro) and want to wipe its virtual disk and settings cleanly from your Windows machine, unregister it with:
wsl --unregister <DistributionName>
(Caution: Microsoft notes that unregistering a distribution permanently deletes all data, settings, and software inside that Linux instance.)
The Bottom Line for Windows and Linux Users
Does Ubuntu have flaws? Plenty of Linux veterans will happily lecture you about Canonical's push for Snap packages or point out that distributions like CachyOS, Linux Mint, Fedora, or Debian offer leaner, faster, or less opinionated desktop experiences.
But in operating systems—just as Windows users have known for decades—raw technical purity rarely decides market ubiquity. Ubuntu earned its crown by mailing millions of free CDs when bandwidth was scarce, capturing the tutorial and developer ecosystem early, offering predictable Long Term Support lifecycles for enterprise servers, and sitting right at the end of Microsoft's default wsl --install command. It does not have to be every enthusiast's favorite Linux distro to remain the starting line where almost everyone meets Linux first.
Correction (October 17, 2026): An earlier correction today removed the How-To Geek/Zunaid Ali attributions as supposedly fabricated. That How-To Geek retrospective is real, so the attributions have been restored and the fabrication claim is withdrawn. The Stack Overflow figure cited is from the 2024 Developer Survey (not 2025), and Canonical's ShipIt program began in 2004 (not 2005).
