Steam ending support for Windows 10 32‑bit on Jan 1, 2026

Valve has announced Steam will stop supporting Windows 10 32‑bit systems starting January 1, 2026. Existing Steam clients on those systems may continue to run for a while, but they will no longer receive updates or technical support.

Key points

• End of Steam support for Windows 10 32‑bit: Jan 1, 2026.
• Valve reports only about 0.01% of Steam users run Windows 10 32‑bit.
• Microsoft ends mainstream security/technical updates for Windows 10 on Oct 14, 2025 — users on 32‑bit Windows 10 will lose both OS and Steam support.
• Steam will continue to support Windows 10 64‑bit (and newer 64‑bit systems); Windows 11 is 64‑bit only.

What this means for gamers

If youre still on Windows 10 32‑bit, your Steam client will stop receiving updates and fixes starting Jan 1, 2026. You should plan to:

• Check if your CPU supports 64‑bit (most modern processors do).
• Back up important games and saves.
• Upgrade to a 64‑bit version of Windows (clean install may be required) or consider newer hardware that ships with a 64‑bit OS.
