Valve has announced the end of support for 32-bit Windows operating systems on its Steam platform, transitioning to a native 64-bit architecture to improve security and performance. Support for the 32-bit client will continue until January 1, 2026, after which it will no longer receive updates or security fixes. Users on 32-bit systems may experience a decline in service quality and access to new features. The decision is driven by memory limitations of 32-bit systems, which can only address a maximum of 4 GB of RAM, and the enhanced security capabilities of 64-bit systems. The latest Steam update also includes support for the Nintendo Switch 2 controller, compatibility with GameCube Adapters in Wii-U mode, and improvements to "Gyro Modes" along with various bug fixes. Users are encouraged to upgrade to 64-bit systems to avoid service disruptions.

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.
