Steam will stop working on computers running Windows 7, 8 and 8.1 next year

The update to a newer supported version of the OS is also needed because future versions of Steam will need some features and security updates only available on Windows 10 and 11. — Valve

Digital gaming platform and storefront Steam has announced that it will stop supporting Windows 7, 8, and 8.1 on Jan 1, 2024.

This means that Steam will no longer run on computers using these three operating systems (OS) after that date.
