Valve's SteamOS has increased its market share by 0.32%, while Microsoft's Windows 11 has decreased by 0.44%. Approximately four million players are now using SteamOS out of Steam's 132 million user base. This growth is linked to the popularity of handheld gaming devices, particularly following the launch of Valve's Steam Deck in 2022. Valve plans to enhance SteamOS's compatibility with various devices, while Microsoft is introducing a 'full-screen experience' for its Xbox PC app.
