Valve to drop Steam support for 32-bit Windows versions next year
"Valve to drop Steam support for 32-bit Windows versions next year — says it's no longer compatible with core client features, only 0.01% of players actually used it"

"Valve is dropping support for Steam running on 32-bit versions of Windows, starting January 1, 2026. Steam has been available on Windows for more than two decades and, therefore, was built with 32-bit systems in mind. Today, every modern computer is 64-bit, with compatibility layers built in to support older 32-bit apps. So, even though 32-bit apps have carried forward, there's really no place for 32-bit operating systems anymore — which is why Valve is axing support for them.

It's important to understand the distinction between 32-bit apps and operating systems. Steam itself is 32-bit, partly because it's from that era, but mostly because it doesn't need to be updated to a 64-bit instruction set, given its lightweight nature. A lot of games on Steam are also 32-bit. None of that will be affected by the sunsetting of 32-bit Windows support, since it's only support for the operating system itself that's being phased out. Windows 10 32-bit is the only version Steam currently supports anyways, and Valve says just 0.01% of players are still using it today.

Windows 11 is exclusively 64-bit, on the other hand, and now holds more than 60% of the OS share, according to Steam's August 2025 Hardware Survey. Valve has made it clear that 32-bit Windows is no longer compatible with drivers and libraries required for the core features of the Steam client, rendering continued support for it unfeasible.

Come January 1st, the client itself will still work for a while, but will stop receiving security updates, and Valve won't entertain support requests for it. The company advises gamers to upgrade to 64-bit Windows to keep receiving timely updates and assistance. This move somewhat aligns with Microsoft's own plans for Windows 10, which will completely lose official support next month. Steam should still continue to run on 64-bit versions of Windows 10, however, which makes up 35% of all Steam users right now."

Pretty big news and and surprised it took Vavle this long to even offer a 64bit Steam client version.

I imagine Steam had kept it for the backward bompatibility like many linux distro's were.... Now some linux distro's are announcing dropping 32-bit (i.e. Debian 13 Trixie, etc), so other OS's and Steam following suit makes sense... sign of the times

As far as I know, the library that generates steam hashes still 32 bits, that's why (too) you need some 32 bits libraries on Linux for Steam as well... I don't think Valve will upgrade steam to full 64 bits libraries...
But I'll be glad if they do it...

What should people do with a 32 bit system?
The only thing
I would suggest is
Upgrade to 64Bit processor

The truth actually is: you do not need a 64 bits processor for most things a regular user does on a computer...

Technically, yes, practically, most software is 64 bits nowadays.

Not to mention that 4GB of memory hasn't been a usable amount in a long time. Especially for gaming. Now, we could argue until our fingers fall off about who's fault that is, but it won't change the fact that this is where modern computing stands. Yes yes, PAE is a thing, and with the right combination of hardware and OS you can address more than 4GB on a 32 bit system. Though even then I believe that's only at the OS level, and any individual application would still only be able to address 4GB or less. I think on Windows it was actually capped at 2GB per application. However, you still have to go out of your way to find a system that is 32 bit only. Near as I can tell for Intel at least the last 32 bit only processors they made for home computers was the Pentium 4.

Anyone still running a 32 bit home system probably has a reason for it, but they're in the extreme minority and are largely on their own. Certainly the industry has no interest in supporting them. Best of luck to them in whatever projects or hobbies they have that mandate such a system.

So, the current Linux Steam Client is 32-bit as well. I'm wondering if/when they are switching that.

thats just not true, majority of software is meant for 64 bit processors and the 32 bit processors are extremely weak and very old at this point

No, the majority of software was recently upgraded to 64 bits, but 90% of them would work exactly the same (for a regular user perception) as if it was 32 bits... Unless you're doing the craziest spreadsheet on earth, you don't need 64 bits for Microsoft office (or whatever that is called nowadays), you don't need 64 bits for your browser, for your video/audio streaming application, etc...

Now, if you're into HEAVY gaming, simulation software, video editing, 3D editing... Than, 64 bits is really welcome!

PS: You're a Linux user; you can compile/run most of its software's catalog in 32 bits, if you want to (userland 32)... And see for yourself if you really find any abysmal differences...

I would assume that over 80% of the games available on Steam are 64-bit and won't run on 32-bit machines. Only the 32-bit Steam client will go, the support for 32-bit games on 64-bit machines stays. Proton support for 32-bit games will also stay.

Well. Had to happen someday. But, at least it happened fairly late. Seriously, how many people still rely on 32 bits these days? Outside from the obvious (Those that can't afford a new computer.), not a whole lot.

That said, the requirements for Linux are so modest. So, there is a wide range of hardware at a wide range of price. So, the number of people that can't really can't afford it is not that high. Still sucks for those who can't but it is what it is.

Anyway, almost everyone posting here probably rocks a 64 bits capable system.

My retro gaming machines still rock 32-bit Windows XP and DOS/Windows 95. They're not on the internet for obvious reasons, so Steam has never been an option.

Yeah, retrogamers too. Forgot ya bunch and I'm one. Eggs on my face and all.

Many distros and Kernel itself announced plans to drop 32bit support when Steam app is 32bit.

So we now get a confirmation that Steam is moving to 64bit and will be compatible with 64bit only systems. Othwerwise new, incoming Fedora or Debian wouldn't be able to even launch current version of steam app.
