News Microsoft updates Windows 11 CPU support for OEM systems to include 8th to 10th Gen Intel CPUs

The OEM requirements doc remains irrelevant for anyone not manufacturing complete systems, and have little to do with that CPUs Windows actually supports. Unless you're already intimately familiar with WHCP requirements, the OEM doc has no effect on you.
However, Microsoft still hasn’t released an official list of supported CPUs for non-OEM or custom PC builders. So, if you’re building your own Windows 11 PC from used parts, your only guidance is Microsoft’s Windows 11 System Requirements
The Windows 11 System Requirements are literally the requirements for custom PC builders.
 
From the article, referring to 8th/9th/10th gen that they excluded:

The aforementioned Intel CPUs were launched some eight years ago;

That's incorrect. My 10900 was released April 2020 and my two 10850k's were released June 2020. That's only 4.5 years ago.
 
I've seen no indication that security updates are ever stopped on "non-compliant" hardware: works just fine here.

The only hurdle I've personally come across is feature update releases not being installed as only SETUP.EXE (and sub-programs called from there) really checks CPU, TPM and other requirements.

I consider that a bonus and prefer LTSC and IoT anyway.

The only other known hurdle, which I haven't personally faced is the requirement for POPCNT support starting with 24H2 releases, I don't operate hardware that old any more.

I'm running Windows 11 (and Windows 2025 server) on Ivy Bridge and every Intel generation since (as well as Zens) from puny Atoms to hefty workstations without issues or TPM. Anything that ran Windows 10 is also running Windows 11 24H2 (apart from POPCNT), using Windows 10 drivers when needed.

I don't install, but clone from a well maintained and periodically updated base image: saves tons of time and effort, never complains about hardware compatibility and comes without nuisances such as OneDrive, Edge, Co-Pilot, Teams, secure boot, HVCI and plenty other nasties.

I also run both as "to go" variants (thanks Rufus!) on nice 1TB/s Kingston Data Traveller USB sticks.

The OS is much nicer and more flexible than what Microsoft wants to allow...

"eight years ago" probably refers to the oldest 8th gen. By the way, did your 10th gen CPUs got the 24h2 update? my i3 10100 did not, while my Ryzen 5 5600x got it 3 months ago...
