Windows 11 24H2 Instruction Requirement Affects Older/Incompatible CPUs
Systems running on older hardware could be excluded from upcoming public versions of Windows 11—the recently released preview/insider build (26052) has introduced all sorts of new features including "Sudo for Windows", an improved regedit, and hidden beneath the surface, an AI-flavored Super Resolution settings menu. Early partakers of version 24H2 are running into instruction set-related problems—Windows operating expert, Bob Pony, was one of the unlucky candidates. Microsoft's preview code seems to require a specific instruction set to reach operational status—Pony documented his frustrations on social media: "Using the command line argument "/product server" for setup.exe, BYPASSES the system requirement checks for the Windows 11 24H2 setup program. But unfortunately, after setup completes then reboots into the next stage. It'll be indefinitely stuck on the Windows logo boot screen."
He continued to narrow in on the source of blame: "Windows 11 Version 24H2 Build 26058's setup (if ran in a live Windows Install) now checks for a CPU instruction: PopCnt." The Register provided some history/context on the SSE4 set: "POPCNT/PopCnt counts the number of bits in a machine word that have been set (or different from zero.) You might see it in cryptography and it has been lurking in CPU architectures for years, pre-dating Intel and AMD's implementation by decades." It is believed that Microsoft has deployed PopCnt as part of its push into AI-augmented software features, although a segment of online discussion proposes that an engineer has "accidentally enabled" newer CPU instruction sets. Tom's Hardware marked a line in the sand: "PopCnt has been supported since the Intel Nehalem and AMD Phenom II (microarchitecture) era—14 years ago—so compatibility won't be an issue for any modern systems. The only users that will be affected are enthusiasts running modified versions of Windows 11 on 15+ year-old chips like Core 2 Duos or Athlon 64." Bob Pony's long-serving Core 2 Quad Q9650 processor—a late summer 2008 product—was deemed unworthy by the preview build's setup process.

Who cares if that processor could theoretically run windows 11. Anyone using that doesn't need windows 11 and likely doesn't even know what windows 11 is
Older hardware can stay on older operating systems just fine, and you can always find use for them. Old Mac mini computers make for great emulation machines, for example.
Pretty sure it could fetch $100 as a fashion accessory!
Not adequate for a modern days gamer - who's always looking out for the latest titles (to install, try and never finish - unless it's one of those rare games that's captivating from beginning to end) - but definitely good enough for a nostalgic gamer (who finds joy in replaying old titles) - or even one of those online gamers - who plays only titles with potato requirements (like Counterstrike and LoL - only games they ever play - but still identify as gamers... even hard core games - just because they spend 12 hours a day fighting their personal demons).
What boggles me the most... those masochists who yearn to install Windows 11 on those tablet-like hybrids which come with Intel toy-like CPUs and 2GB Ram.
I'm fed with the "security" argument. This is marketing BS to trick people into even more built-in data mining. There's no secure systems. And MS Windows, not the secure OS. And especially W11, which is a resouce hog, but it doesn't give any advantage. There's a lot of really dangerous blotware, that serves no good purpose. At this point they could make security patches for W7, as the windows core is still ancient, and it still would be more secure than W11. The Defender itself is a swiss cheese, that behaves as a Win32 troyan. It gives a lot of false-positives, while truly dangerous stuff can come in like no big deal. And Defender's Firewall only hampers the work of completely safe programs. There's no way to make Windows more secure, if MS made so many holes intentionally in the first place. Heck even Linux is not secure completely. Just don't go to malicious sites.
My point is, the MS Windows is infamous for inflating their specs out of no good reasons. As mentioned above, the core features, services and programs in Windows are still ancient, outdated and sometimes broken. The main thing tha being pushed as reason, is AI/Copilot. And how many people need that, or can opt-out? And that thing is another security loop-hole by it's own. Not only it gives complete access to all the user's data to MS and any thrird-party, but there's no clearness about how it's being used, and what it does itself. How such OS and devices can be treated as safe and "secure"?
The lack security is not only SW/HW problem, it's the behavioural issue. And it's big companies with valuable data, that are primary targets. And the companies should have everything backed up and decoupled from the internet access in the first place. And if they not...
And about HW. Those CPUs were taxed heavilly, in order to close the holes. So they ended up loosing that preformance "advantage" over older counterparts, in order to close the known security holes. Surely the more secure architecture and instructions sets should be present in CPU, and the HW overall must be up to date. But then again, for many stuff that people use, there shouldn't be a concern. And if the popular resourses like YT or social media like reddit, etc are not secure, then, there's nothing else much left to do. As these resourses should be giving only proven and tested data.
And neither UEFI, nor TPM, are anywhere more "secure" than lagacy BIOS, and give no real benefits. TPM is just the addition for the HDCP that intrudes to check if there's no pirated content. How that's needed, if people use official software and HW? And the pirates, will find their way, in any case.
But as you correctly said, the vast, vast majority of all security threats stem from the user behavior. Actually getting malware on a modern OS without the user themselves going to a shady site/clicking on a shady link/downloading a shady executable is extremely difficult. We are not in the Windows XP times anymore.
I have Linux on my phone and router (OpenWrt is awesome), but its desktop experience is garbage, still doesn't even have a unified packaging system and Gnome doesn't even have a taskbar. Complaining about an AI feature that is easy to disable on the best OS available, then suggesting an old MS OS, or Linux? Gtfo.
Yeah thinking MS has been taking notes of to many leather jacket man commercials saying just buy rtx lol
In MS world that means new disposable hardware that likely won't last 2-3 years because it's made so cheap but price sure doesn't reflect it's poor construction one bit.
These old chips are still around because they were made better than some newer stuff is and the old saying is, If it ain't broke, don't fix it :doh:
Can also be said, If a system still works why replace it.
TPM no piracy scans are malicious software removal tools job :laugh:
These days, I wouldn't even dream of running a system running modern software with anything less than 8 GBs of RAM, 16 GBs is preferable.
Mother boards are definitely made better back then
More chips killed by crappy newer mother board and their bios than anything else.
