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.
