Latest Steam Client Beta Unofficially Backported to Windows 7 and Windows 8
The latest Steam Client beta build dated to December 4th has unofficially been backported to Windows 7 SP1 x64 and Windows 8.x x64. While these operating systems have long been abandoned by Microsoft, an enthusiast "EAZY BLACK" has managed to make an unofficial backport of Steam's Client beta build. Both Windows 7 SP1 x64 and Windows 8.x x64 are platforms that Valve officially stopped supporting in early 2024. This means that any future support will come solely from the gaming community, as a dedicated effort to ensure that no one is left behind, even if they are using an unsupported operating system.
The distribution comes as compact 230 MB packages hosted on w7revived.chefkiss.dev and mirrored by BobPony. Each package is accompanied by an intriguing security warning that Windows builds must be first updated to their latest versions, which happened years ago on both Windows 7 and Windows 8. A screenshot shared with the post shows Steam operating on Windows 7 with the About dialog visible and several Half-Life titles listed, indicating that core features are functioning. Community reaction has been mixed, with many users expressing gratitude for renewed compatibility.Running an unsupported operating system alongside an unofficial client poses a significant security risk. Users are always advised to keep their software updated with the latest patches to prevent security vulnerabilities. Therefore, we urge those considering trying this backported client to exercise caution and carefully consider the risks before using unofficial software.

this has worse font rendering but maybe it will work
backup original first and also restore original chromehtml.dll
please tell your exact system specs and what installed
i tried my client on 3 installs
1: vmware, only important updates and vc redists
2: i5-4460 + R9 380 4GB simplix, net 4.8 and vc redists etc
3: i3-550 + GT 1030 manually updated up to latest esu, everything installed including optional updates and net 4.8 , vc redists etc
it launches instantly and works fine on all of them
As that option moves the client data to its default location, now I'm wonderiing if the problem was caused by the old client being installed to a custom directory.
Anyway, your ported client works properly now :)
It launches in 12 seconds on my PC and appears to be fully functional. Thanks for your help so far, I'll be sure to check out new versions as they come out.
Glad that you got it workingYes the installer has an upgrade option. Will work fine if installed to default program files (x86)/steam
It would be a good idea to put this information in the readme, or include a warning in the installer script.
steam is cef 126, wrappers work probably up to 128
I updated the wrappers to support 138 now, which is what the next steam build will use
They havent updated steam beta since dec4 which is rare so that means new cef coming
some older versions on the site were backported/compilied by my friend
If you enjoy backporting software to old versions of Windows you'd probably have a great time with the guys over at BetaArchive? They have quite a few members trying to get newer drivers/software running on abandoned and beta versions of Windows, some of which weren't made public until much later. I'm sure they'd appreciate your skillset :)
Is it dead ?
