Valve has announced that as of January 1, 2026, Steam for 32-bit based versions of Windows will no longer be supported. Currently, the only version of Windows 32-bit that Valve actively supports is Windows 10, but that will no longer be the case as of next year.
Interestingly, Valve says that there are only 0.01% of Steam users that are still using a 32-bit version of Windows 10, and so this end of support date won't impact most people. Additionally, although the Steam client will no longer be supported with new features or fixes, it will likely continue to work on 32-bit Windows for the foreseeable future.
