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.

In reality? This is a nonissue. Any PC with CPU affected isn’t worth running 11 on anyway.
More people than people willing to use a dell logo as a avatar I'd bet :laugh:
This is artificial obsolescence because of the greed.
Windows 11 shouldn't have existed in the first place.
The best way to communicate your disapproval to Microsoft is to not use their OS at all and run Linux.
I doubt there are many casual users who still run such old hardware. Maintaining it this long does require care and people rarely do this. Those who do are probably knowledgeable enough to stick to outdated software and airgap the machine or migrate to other OS'es that still do support their hardware.
Or, and I'm betting those are the majority, using them for some fixed purpose workstation or interface for some equipment, and they'd already be on an outdated Win7 or XP.Did you mean "Sudo for Windows and an improved Registry editor?"
Because sudo is not a registry editor. Improved or otherwise.
Yeah besides some UI differences it is pretty much win-10 sp2
Backwards compatibility is still excellent, there's nothing stopping those using 15 year old hardware from running a LTSC install or even Linux (which is arguably more cutting edge if kernel development is anything to go by) it's just people like to find something to complain about.Also noticed this. Going to follow up and edit if necessary.
Yeah sudo added to terminal to run as admin ?
Yeah Brink has a tutorial about it's addition in developer tools
But that is basically what it does
Open regular terminal and oops you need admin so just enter sudo and you're done.
Funny sudo su is what linux uses hehe

Option 3 if you don't see it.
Yeah dude on linux mint forum gave me this to just set the clock to USA time see if you recognize this stuff lol
