Valve to end Steam support for 32-bit versions of Windows 10 OS

Valve is ceasing Steam support for systems running 32-bit versions of the Windows 10 operating system (OS) on January 1, 2026.

In a recent Steam Support blog, Valve explained that Windows 10 32-bit is “the only 32-bit version that is currently supported” on the platform and that, according to results from its August 2025 Steam Hardware Survey, only 0.01% of users reported using the operating system.

Valve has said that “for the near term,” existing Steam Client installations will “continue to function” on Windows 10 32-bit, but they won’t receive updates “of any kind,” including security updates.

“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.

The company clarified, however, that “Windows 10 64-bit will still be supported and 32-bit games will still run,” after support ends in January 2026.

However, “to ensure continued updates and compatibility,” Valve recommends that users update to a 64-bit version of Windows.

“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.”

Earlier this week, Valve announced an update to Steam’s revenue reporting system, making it easier for developers to “see the monetary impact of each discount that you have run.”
