Steam will stop supporting 32-bit versions of Windows from next year. Valve says the libraries and drivers needed for core client features are no longer compatible with 32-bit architecture, and therefore need to be left behind. Upgrade to Windows 10 64-bit, or Windows 11, to keep receiving timely updates and assistance.
