Windows and Linux are operating systems: the software that manages your computer's hardware, files and applications. Windows is developed by Microsoft and is familiar to many people from store-bought PCs. Linux is the kernel at the centre of a family of systems, commonly called distributions, such as Ubuntu, Fedora and Debian.
Both can be useful. Windows is often a straightforward choice when it already supports the applications and devices you need. Linux is worth exploring if you want an adaptable system, open-source tools or a different approach to running a desktop or server. My advice is to choose for your actual workflow, rather than treating either name as a universal winner.
What a Linux distribution is
A distribution combines the Linux kernel with applications, an installer, update tools and other components. Communities and companies maintain different distributions, so “Linux” is not one desktop interface or one support policy. A beginner-friendly desktop and a minimal server can look and behave very differently while using the same kernel family.
Open source means that source code is available under licences permitting use, inspection, modification and redistribution subject to their terms. It does not mean every application or driver installed on a Linux system is open source, or that every service and support package is free. The Linux kernel itself uses GPL version 2; other components have their own licences.
Many desktop distributions can be downloaded without a licence fee. Windows commonly involves a commercial licence, often included with the PC. When comparing costs, also consider your required applications, support, time spent learning and the hardware you already own.
Everyday comparison
| Consideration | Windows | Linux distributions |
|---|---|---|
| Familiarity | Often already installed and familiar | Interface depends on the distribution and desktop |
| Applications | Broad commercial desktop catalogue | Many open-source tools; check required commercial apps |
| Hardware | Check the exact Windows version and driver | Check the exact distribution, kernel and device |
| Updates | Windows Update plus application update mechanisms | Distribution tools plus other installed software sources |
| Customisation | Settings, administration tools and PowerShell | Choice of desktops, packages and system configuration |
| Support | Microsoft, PC vendor and application-specific support | Distribution community or paid vendor support, depending on the product |
The interface should help you get work done. Linux does not require every task to be performed in a terminal, and Windows also has powerful command-line tools. Familiarity can matter more than how many settings a system exposes. Try ordinary tasks before deciding that one interface is easier for you.
Check applications and documents first
Make a list of software you must use, including workplace applications, peripherals' configuration tools and any specialist creative or engineering programs. Check the publisher's supported operating systems and versions. A Windows installer is not automatically a native Linux program, and a similarly named alternative may not have all the same features.
Web applications can reduce the difference for browsing, email and some office work. Still test representative documents, fonts, spreadsheets, macros and collaboration features. A document opening successfully does not establish that complex formatting or a required workflow behaves identically.
If your essential software is already supported on Windows and you want minimal disruption, staying with it is reasonable. If suitable Linux applications cover your needs, a distribution may offer the flexibility and lower entry cost that make it attractive.
Gaming compatibility
Windows remains a common target for desktop PC games, but that does not make every game compatible with every Windows PC. Hardware, drivers, the operating-system version and publisher requirements still matter.
Linux can run native games and many Windows games through tools such as Valve's Proton. Compatibility is title-specific. Valve documents support for some anti-cheat systems, including Easy Anti-Cheat and BattlEye, but developers must enable the relevant support for their titles. Neither “all anti-cheat works” nor “no multiplayer game works” is accurate.
Check the current status of the games you actually play, including launchers, online modes and peripherals. Do that before replacing the operating system on your only gaming machine.
Hardware and support lifetime
Check the exact computer rather than assuming either OS supports everything. Wi-Fi, graphics, printers, fingerprint readers, webcams, audio and sleep behaviour can differ by model. A virtual-machine trial helps with the interface and applications, but does not fully test the real hardware's drivers.
For Windows 11, Microsoft's requirements include a supported processor, TPM 2.0 and UEFI firmware capable of Secure Boot, among other conditions. Use the official compatibility guidance rather than assuming a fast older PC qualifies. App requirements can also exceed the operating system's minimum.
Standard Windows 10 support ended on 14 October 2025. Some editions and extended-security arrangements have different conditions, so check the exact product's lifecycle. Likewise, Linux releases have support periods: an old distribution without updates is not automatically a secure way to keep old hardware running.
A supported lightweight Linux desktop can be worth trying on suitable older equipment. Choose a distribution that still supports the machine and your applications, then test it. Do not promise that switching alone will make every ageing computer fast.
Updates, security and privacy
Both systems can be attacked or misconfigured. Open source allows inspection, but it does not guarantee immunity from malware, a smaller attack surface in every installation or perfect privacy. Keep supported software updated, use appropriate permissions and maintain backups on either system.
Both can require restarts to apply some updates. Linux package managers do not guarantee that one command updates every application installed by every method, and there is no need for a beginner to run an automatic “yes to everything” upgrade command from a comparison article. Use the distribution's recommended update tools and understand any proposed changes.
Windows also has package management: Microsoft's WinGet can discover, install, upgrade and remove supported applications. Linux distributions commonly offer graphical software tools and package repositories. Prefer trustworthy sources, and assess extra third-party repositories or downloads on their merits.
For privacy, review the actual system, application and account settings. Changing operating systems does not remove the data collected by every browser, cloud account or installed program.
Development and homelab use
Linux is popular for development and hosting services because many server tools are built around its environment. Windows can also be useful for development, including Linux tools through Windows Subsystem for Linux. There is no requirement to replace a familiar desktop simply to begin learning server administration.
Linux containers use a Linux kernel. Docker Desktop can provide that environment on Windows through WSL 2 or other supported backends. Windows containers also exist, with separate host and image requirements. A container is not a full virtual machine, but running many services still uses CPU, memory, storage and networking; no platform promises zero overhead.
For a host running continuously, consider supported software, resource needs, update planning and recovery. Measure the actual workload rather than using a universal idle-RAM table to declare one operating system more efficient.
Try before switching
A useful first step is to test a Linux distribution on a separate machine or in a virtual machine to see whether it suits your work. Ubuntu also documents a live USB preview. Preparing the USB overwrites that USB's contents, so choose the correct device and preserve anything you need first.
Use the preview to check basic hardware and familiar tasks. Some proprietary drivers may be absent from a live session, so interpret failures in that context. Before an actual installation or dual-boot change, back up your data and understand the disk choices.
Windows is a sensible choice for many people who want a familiar, supported everyday workflow. Linux remains attractive for learning, customisation, suitable applications and budget-conscious experimentation. Trying your own tasks provides a better decision than claims that either system always wins.
