Steam will no longer support 32-bit operating systems from 2026
, by Thibaut
Valve announced the news in a statement on Thursday. From January 1, 2026, 32-bit operating systems will no longer be supported by Steam.
The American company explains its decision by the fact that 32-bit OSs currently represent only 0.01% of the systems listed in the Steam Hardware Survey.
"Existing Steam Client installations will continue to function for the near term on Windows 10 32-bit but will no longer receive updates of any kind including security updates. Steam Support will be unable to offer users technical support for issues related to the old operating systems, and Steam will be unable to guarantee continued functionality of Steam on the unsupported operating system versions."
Users will therefore have to switch to a 64-bit operating system to access recent updates. However, Valve states that 32-bit games will still work.
