Two operating systems, two philosophies. One is free and open, built by a global community. The other is polished and everywhere, backed by a trillion-dollar company. Here is how they actually compare — no fandom, just facts.
Before comparing features, it helps to understand what each operating system actually is.
An open-source kernel surrounded by hundreds of free distributions — Ubuntu, Fedora, Mint, Arch. The source code is public, anyone can modify it, and no single company owns it. Created by Linus Torvalds in 1991, it now runs most of the internet's servers, every Android phone, and 100% of the world's top 500 supercomputers.
Microsoft's closed-source operating system, first released in 1985 and now on roughly 1.4 billion active devices. It is what most PCs ship with, what most offices standardize on, and what most PC games target. Polished, familiar — and a paid product you license rather than own.
Linux is free and open — you can read every line of code and reshape it to fit you. Windows is closed and curated — you trust Microsoft's choices and in exchange get consistency plus the biggest software library on Earth. Neither philosophy is objectively better; they serve different priorities.

Market share varies wildly by category — each OS dominates where you would least expect.
Windows is the default most people never leave.
The internet runs on Linux.
Every Android phone is a Linux machine.
All 500 of the world's top supercomputers run Linux.
There is no universal winner — there is a winner for you. Be honest about what you actually do with your computer, and the answer is usually obvious.
You are learning to code, want to revive an old laptop, care about privacy and open source, run servers, or simply refuse to pay for an operating system. Ubuntu or Linux Mint make it easy.
You play competitive PC games, depend on Adobe or MS Office, work somewhere that mandates it, or just want everything to work with zero tinkering. It is the safe default.
You are unsure. Dual-booting, or running Linux in a VM or WSL2 inside Windows, costs nothing and teaches you both. Nothing is permanent — try it for a week.
