Valve has transitioned the Steam client on Windows 10 and Windows 11 to a fully native 64-bit architecture, ending support for 32-bit Windows installations. Users on 32-bit systems will receive security updates and bug fixes until January 1, 2026, after which the Steam client will be considered insecure. Less than one percent of active Steam users are affected by this change. The shift to 64-bit allows for better RAM access, improved stability, and eliminates the need for the WoW64 compatibility layer. The update also includes technical enhancements such as a fix for H.265 game recording on Nvidia 50 series graphics cards, support for Nintendo Switch 2 controllers, and improved chat moderation features. Valve has ceased support for Windows 7 and Windows 8 as of the end of 2024.
