Earlier this year, Windows 10 user base on Steam finally crossed the 50% milestone, 17 months after release. However, in subsequent months, the operating system's user base declined considerably, down to 48.77%.
Now, according to the latest Steam hardware survey, Windows 10 is now being used by 51.2% of surveyed Steam gamers, an all-time high for the OS.
Apple's OS X user base declined slightly to 3.11%, the only iterations that saw an increase were versions 10.12.3 and 10.12.4. On the other hand, Linux remained stagnant with its relatively minuscule 0.77% user base.
In terms of hardware, 8GB of RAM is still the most-used configuration by Steam gamers. The display resolution for primary displays and multi-monitor setups was 1920x1080 and 3840x1080 respectively.
It is worth noting that Steam's report is based on optional user surveys so it may not accurately depict the real situation. That said, it'll be interesting to see how the release of the Creators Update later this month affects the aforementioned figures.
