Valve is ceasing Steam support for systems running 32-bit versions of the Windows 10 operating system (OS) on January 1, 2026. "Steam Support will be unable to offer users technical support for issues related to the old operating systems, and Steam will be unable to guarantee continued functionality of Steam on the unsupported operating system versions," Valve said in the post. "This change is required as core features in Steam rely on system drivers and other libraries that are not supported on 32-bit versions of Windows," Valve continued. "Future versions of Steam will run on 64-bit versions of Windows only. We strongly encourage all 32-bit Windows users to update sooner rather than later."
