Steam operating system available to download and play on without Windows
SteamOS is an operating system that lets you run Steam games without the need for a Windows operating system. Based on Debian (a Linux distribution), SteamOS offers the entire catalog of Steam games, as well as all compatible Debian applications accessible on a TV. Although it’s still in the very early stages, SteamOS has plans to become a major operating system for gamers that will be compatible with PCs and Steam Machine game consoles.
Install SteamOS on your PC
SteamOS is currently in a test version, and not all of the features are activated yet. The installation can also be quite daunting, so we’d advise you to refer to the official FAQs.
