Windows 11 hits a new PC gaming milestone on Steam with over 70% market share — Windows 10’s time is running out
Windows 11 has achieved a significant milestone in PC gaming, surpassing 70% market share according to Valve’s Steam Hardware Survey for June 2026. This represents continued growth for the operating system as Windows 10 approaches its end of support, with users steadily migrating to the newer platform. The data underscores Windows’ sustained dominance in the gaming landscape, despite ongoing discussions in the community about alternative operating systems gaining traction.
Linux experienced a slight month-to-month decline, dropping 0.30 percentage points to 3.69% market share in the June survey. However, the broader trend remains positive for Linux gaming, as the platform continues to outperform its position from the same period last year, when it held 2.57% market share. This year-over-year growth demonstrates steady progress for Linux in the gaming ecosystem, even amid short-term fluctuations.
The survey results reflect broader industry dynamics as Windows 10’s support window narrows. The operating system’s declining share suggests an accelerating migration to Windows 11, though the transition has been measured. These market shifts will likely influence how game developers and publishers approach platform optimization and support strategies going forward.
