Windows just saw a dramatic drop in OS market share on Steam as gamers move to Linux

The March 2026 Steam Hardware & Software Survey shows Linux surpassing a 5% market share on Steam for the first time, with SteamOS leading the way. Windows' market share dropped to 92.33%, with Windows 11 at 66.85% and Windows 10 losing almost 15%. While Windows remains dominant, some gamers are exploring Linux due to concerns about Windows 11's stability for gaming. With the rise of gaming-focused Linux distros and upcoming Linux-based Steam products, the shift to non-Windows platforms in PC gaming is gaining momentum.
