Steam beta client is now fully 64-bit on Windows 11 and 10 — 32-bit support ending soon

The developers have also begun testing enhanced controller support.

In late November, Valve rolled out a beta update for the Steam client. The application is now fully 64-bit and runs on Windows 11 and 64-bit Windows 10.

Valve confirmed that the 32-bit Windows client will continue to be supported through January 1, 2026.

Several technical bugs were addressed, and controller support received the following enhancements:

• Support added for Nintendo Switch 2 controllers when connected via USB on Windows devices.
• Fixed an issue that prevented gamepads from being detected in Unity-based games.
• Added support for GameCube adapters in Wii U mode with rumble on Windows.
