Valve plans to discontinue Steam support for 32-bit versions of the Windows 10 operating system

By January 1, 2026, Valve will stop supporting Steam on 32-bit Windows 10 systems. This decision was outlined in a blog post from Steam Support, which noted that Windows 10 32-bit is the sole 32-bit operating system currently available on Steam. Data from the August 2025 Steam Hardware Survey showed only 0.01% of users utilized this OS.

Though existing Steam Client installations will still operate temporarily on Windows 10 32-bit, they will no longer receive any updates, including those for security. Consequently, Steam Support will not provide technical assistance for issues related to these outdated systems, and the platform cannot assure functionality on unsupported OS versions.

Valve maintains that Windows 10 64-bit will remain supported, and games created for 32-bit systems will continue functioning after the cutoff in early 2026. The company advocates for users to switch to a 64-bit Windows version to maintain update capabilities and ensure compatibility, as Steam’s core features depend on system drivers not available in 32-bit OS.

In addition, Valve emphasizes that future Steam iterations will function solely on 64-bit Windows versions. The company urges users on 32-bit systems to upgrade promptly to avoid any disruptions.

In a related development, Valve disclosed an enhancement to its revenue reporting, enabling developers to assess the financial effects of discounts more effectively.
