PC games giant Valve will no longer be supporting 32-bit versions of the Windows operating system for Steam. 

In a post on its website, the company said that it would be ending support on January 1st, 2026, saying that the 32-bit version of Windows 10 is the only OS it supports. According to its Steam Hardware Survey, only 0.01 per cent of systems using its platform use this operating system. 

"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," Valve wrote. 

"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.

"To ensure continued updates and compatibility, users should update to a 64-bit version of Windows.

"This change is required as core features in Steam rely on system drivers and other libraries that are not supported on 32-bit versions of Windows. Future versions of Steam will run on 64-bit versions of Windows only. We strongly encourage all 32-bit Windows users to update sooner rather than later."
