As of January 1, 2026, Steam will stop supporting systems running 32-bit versions of Windows. Windows 10 32-bit is the only 32-bit version that is currently supported by Steam and is only in use on 0.01% of systems reported through the Steam Hardware Survey. Windows 10 64-bit will still be supported...

No one uses 32 bit Windows (especially for gaming), but at least we might at last get a 64 bit verison of the Steam client on Windows.
