Steam app is now 64-bit only on systems that support it, 32-bit support enters final countdown — 32-bit users will stop receiving updates in 2026

Valve has transitioned the Steam app to be 64-bit only on systems that support it, with 32-bit support set to end in 2026. The recent client update for Windows 10 and 11 marks the shift to a fully 64-bit application, leaving 32-bit Windows users on a compatibility branch that will cease receiving updates in 2026. While Steam will still function for 32-bit Windows users, there will be no further updates, security fixes, or customer support after the cut-off date. The move aligns with broader changes in the Windows ecosystem and affects a small percentage of Steam users still on 32-bit systems.
