Windows 11 24H2 has new hardware requirements.?

Microsoft's official lists of supported AMD and Intel processors in Windows 24H2.

Which instruction is missing from gen 6 Intel processors that is included in later ones?

Apparently the reasoning behind MS setting the bar at 8th gen and above is native support for mode-based execution control, lacking in earlier generations.

“The strategy for the initial release of Windows 11 is very simple: raise the baseline. Turn on the things that were optional in Windows 10 by default,” Weston said.

One example is a feature called mode-based execution control, which—in tandem with Intel’s eighth-gen CPUs and up—helps to ensure optimal performance while running certain virtualization-based security protections, he said.

While older CPUs can emulate hypervisor-protected code integrity, MS think the performance hit would be unacceptable...

What Microsoft did mention in the posts is virtualization-based security, as well as hypervisor-protected code integrity, or HVCI.....

....Mode-based execution control is a critical underpinning to the optimal use of HVCI. The feature is what ensures that running HVCI doesn’t deliver a major hit to performance and user experience.

HVCI can still work with processors that don’t support mode-based execution control—but those processors depend on an emulation of the feature, “which has a bigger impact on performance,” Microsoft said in July documentation about HVCI.

Those of us who have run W11 on unsupported CPUs may disagree, but this seems to be Microsoft's justification.

There is a lot of incorrect information out there regarding Windows 11, especially when creating a local account on Win Pro 24H2 (which is what I installed 2 days ago)

I found 5 different ways to bypass the ms account and internet requirements across 5 websites and none of them worked. Luckily I found the information in a 55 second YouTube video. Absolutely exhausting. Sorry I veered off topic a bit here.

The infallible way BAR NONE to bypass the Ms account on Win 11 Pro above and others is at the "Work / School /home choice for computer at the OOBE stage is to choose school / work and at sign in option choose Domain join (you don't need a domain).

I don't know about W11 Home -- don't have it, don't care about it, don't want it) but W11 Pro, education, workstation, enterprise, iot enterprise this method works perfectly -- just did one this morning 24 Mar.

Still works and is 100% Ms way - no registry hacks, special Rufus install versions etc etc.

Absolutely FORGET Reddit (probably the most useless I.T site ever since the days from the invention of the abacus), or 99% of incoherent mumbling youtube ad ridden videos and large % of google search results.

W11 Forums is easily the best source for anything technical on Windows 11 (and a lot more besides). Thanks @z3r010 for maintaining this brilliant site (plus the sister ones).

Home has no support for joining a domain, so this trick doesn't work for them.

The requirement for Intel 8th gen processors cannot be simply the power, I checked some of the Passmark Software cpu scores and a Celeron 6305 which is approved has a score of 1196 and my laptops i3 6100U is 2638, more than double the power.

These processors meet the design principles around security, reliability, and the minimum system requirements for Windows 11

Correct - Not just about the power

It's actually many things making up today's CPU's and not all is readily available to compare. Example both my i7-6700K, and 19-9900K both list the same instruction sets on Intel's site - Intel® SSE4.1, Intel® SSE4.2, Intel® AVX2, yet when you take a closer look at the Advanced Technologies section, you'll notice differences - Intel® Trusted Execution Technology supported on the i9-9900K (Win 11 Supported), and NOT supported on the i7-6700K (no Win 11 support). Intel® Trusted Execution Technology is another supported on the I9-9900K, not on the i7-6700K.

I'm sure there's other stuff both known, and not known as to why one does support 11, and the other doesn't, so...

That's not all. One of my pc is intel core i5 3230M still can istall 24h2.

I'll see your 3rd gen i5 and raise you the 1st gen i5-520M in my System Two.
It's currently multi-booting RTM 24H2 and Insider builds up to Canary 27818.1000.

antspants said:

Yes (for anyone reading) for 24H2 you need to have an SSE4.2 capable CPU.
You can bypass TPM2 requirements, but without a CPU supporting SSE4.2 you can not run 24H2

25H2 is yet to be seen.

I lucked out once again. All three of my computers, desktop and two laptops, qualify so far. This is probably the last time but I'll just have to stick with the Windows 11 24H2.

I don't believe there will be a 25H2.

Good morning Wynona.

Your luck should hold for some time yet. I am running the latest Insider Canary build (potentially the next release) running on an unsupported 1st gen i5.
