The latest Steam Hardware & Software Survey for December 2025 reveals a significant rise in Windows 11 usage among PC gamers, while Linux's growth has paused. After a small increase in November, Linux's market share slipped slightly. Windows 11, meanwhile, saw one of its largest monthly jumps.
Steam's December 2025 survey, released in early January 2026, highlights shifting preferences among PC gamers on the platform. In November 2025, Linux experienced a small but notable gain in momentum, raising hopes for continued adoption. However, the December data shows a stall: Linux's install base slipped by 0.01% month-over-month, marking an unexpected pause after several months of gradual growth.
In contrast, Windows 11 recorded a substantial increase, rising by 5.24% overall. This represents some of the biggest gains yet for Microsoft's latest operating system on Steam, where it continues to dominate the landscape for PC gaming.
The survey underscores the ongoing tug-of-war between proprietary and open-source systems in gaming. While Linux's minor dip is negligible in absolute terms, it tempers enthusiasm from enthusiasts who have pushed for better compatibility and performance on the platform. Windows 11's surge may reflect improved hardware support, game optimizations, or user upgrades amid broader PC market trends.
These monthly surveys provide a snapshot of Steam's over 100 million active users, offering valuable insights into software trends without revealing individual data.
