Steam to Discontinue Support for 32-Bit Windows 10 Operating Systems

As of January 1, 2026, Valve will no longer provide support for Steam on 32-bit versions of the Windows 10 operating system. According to a recent blog post by Steam Support, the current support for 32-bit Windows 10 is limited, with only 0.01% of users utilizing this operating system, as per the August 2025 Steam Hardware Survey. While existing Steam installations will continue to function on 32-bit Windows 10 in the short term, they will not receive any updates, including essential security patches. Furthermore, Steam Support will be unable to provide technical assistance for issues related to outdated operating systems, and the functionality of Steam on these systems cannot be guaranteed. However, Valve has confirmed that 64-bit versions of Windows 10 will remain supported, and 32-bit games will still be compatible. To ensure uninterrupted updates and compatibility, the company recommends that users switch to a 64-bit version of Windows. This transition is necessary because key features in Steam depend on system drivers and libraries that are not compatible with 32-bit Windows versions. Valve has stated that future versions of Steam will only be compatible with 64-bit Windows, and the company strongly encourages all 32-bit Windows users to upgrade as soon as possible.
