Valve is finally pushing the Steam client beyond the 32-bit world, at least for Microsoft Windows.

Valve announced via Steam Support that beginning January 2026 they will no longer be supporting 32-bit versions of Windows. There will continue to be 32-bit game support on Steam but the Steam client itself will no longer support 32-bit Windows.

Existing Steam client installations on Windows 10 32-bit will continue to work but will no longer receive any updates or Steam Support. Valve is encouraging all Windows games to move to a 64-bit Windows operating system.

All the details on the ending of 32-bit Windows support as of 1 January 2026 can be found via [1]this Steam Support ticket .

Sadly there is no word at this time on Valve ending 32-bit Linux support or rather putting the Steam Linux client squarely in a 64-bit world. That is something many Linux gamers and distribution vendors would desire as Steam continues to be one of the main Linux 32-bit users out there with nearly all other major software happily living in a 64-bit world without the 32-bit dependencies... Steam on Linux unfortunately continues to carry many 32-bit library dependencies. Here's to hoping that day of avoiding the Steam Linux 32-bit mess isn't too far away.
