Valve's hardware survey data shows that Windows 10 remains the dominant operating system among PC gamers, with a slow decline expected despite Microsoft's upcoming support cessation. Windows 11 has not surpassed 60% in any Steam survey sample, and its growth has been stagnant. Windows 7 currently holds a mere 0.1% share, and projections suggest it could take about 82 months for Windows 10 to reach that level if trends continue. Linux's share has increased from around 1% to over 2.5% in three years, while Windows 11's growth has only seen a 3.7x increase during the same period. The survey indicates that the launch of the Steam Deck has had a limited impact on Linux adoption.
