Valve has officially concluded support for the 32-bit Steam application on Windows 10 and Windows 11 as of December 19. Updates for the 32-bit Steam client will continue until January 1, 2026. Users are encouraged to migrate to 64-bit operating systems, as the number of users on 32-bit systems is low. Those remaining on a 32-bit OS will need to upgrade their hardware or reinstall a 64-bit operating system to continue accessing the official Steam Client. The gaming community may create unofficial backports for 32-bit builds, but using older software carries security risks. Valve ceased support for Windows 7 SP1 x64 and Windows 8.x x64 in early 2024.
