It'd ultimately be better for everyone if no PCs could boot windows 11.

OH NO anyway.

At this point Microsoft should just be buying me the computer since they make all their money on collecting my data

In modern x86 CPUs, POPCNT is implemented as part of the SSE4 instruction set. For Intel's chips, it was added as part of SSE4.2 in the original first-generation Core architecture, codenamed Nehalem. In AMD's processors, it's included in SSE4a, first used in Phenom, Athlon, and Sempron CPUs based on the K10 architecture. These architectures date back to 2008 and 2007, respectively.

That effectively bars mid-2000s Intel Core 2 Duo systems and early Athlon 64-era PCs from booting Windows 11 at all, not that they officially supported it in the first place. This means the change should mainly affect retro-computing enthusiasts who spend their days making YouTube videos in the "we installed Windows 11 on a potato, let's see how it runs" genre rather than users of actual systems.

You can check if your CPU has SSE 4.2(Intel) or 4a(AMD) but it sounds like unless you're running some real old stuff you shouldn't have to worry.

do hack to make software run on unsupported hardware

software stops working with update

surprised pikachu

“this is why i switched to linux” no shut up lol. this is not an issue for any average user and if you had the ability to hack the TPM requirements you have the ability to fix your borked install. this issue affects no one else. 🙂🙂🙂

Itt: Use Linux Spam. This is not feasible for most users. Not all applicatopns are posted to Linux and some explicitly do not work. In particular for people that play games socially this just does not work. That being said they are unaffected by this change.

Sudo switch to linux

May I ask - why is anyone bothering to install Windows 11 on old hardware in the first place?

Old hardware is better for Linux. Either install Linux or you can get used to having your old hardware be used as a paperweight.

I've got a solution but y'all will not like it🐧

I went to Linux for all private use years ago. And man - I wish so very hard I could simply switch to a non win-native CAD at the job.

It's penguin time

Linux Linux Linux Linux Linux Linux Linux

With all due respect, that sounds very much like what something unsupported would do.

sudo dnf install fedora-39-workstation-edition

2025 will likely be way more the year of massive e-waste than the "Year of the Linux Desktop (TM)" - but I still think it is in the realm of possible that Linux market share close to doubles into the 5 to 8 percent range.

While I already regularly use Ubuntu and Ubuntu Touch for my "infotainment" desktops, laptops and tablets - I have 3 desktops in my studio that run Windows 10 that work great for my pro audio work needs, none of which qualify for Windows 11 according to MS's "PC Health Check" app. So I've been investigating running Ubuntu Studio dual booting on one of my machines as a possible way of keeping these boxes going after Win 10 stops getting security updates. Some things look promising, but given I was not able to get the available kernel module device driver to build for my Merging Anubis (which is my main audio interface for my mastering studio) I will likely still need to get a Win 11 box in order to be able to continue my current work flow.

Almost like I still have no reason to get a secure boot machine!
