Windows 11 24H2 has un-bypassable hardware requirements...

RD Mercer · Friday at 11:52 AM

I'm running 24H2 right now on my system, haven't really installed many apps on it, it's in my test mode right now.

I'm running 23H2 on 2 Notebooks from 2014 upgraded from Win10 22H2, no issues with the single-file tweak running setup.exe from the MCT USB thumb drive. I don't know yet if that will remain true when the fully-Released 24H2 version comes out.

It remains to be seen if indeed 24H2 will make extensive use of PopCnt instruction or it is only a compatibility check to stop older computers running Windows 11. This was the case with the first edition of Windows 8. It required NX/PAE instruction to install and boot, but once you bypass the compatibility check you could run it on an unsupported Pentium 4 socket 478 CPU. Let's hope this is the case with the PopCnt instruction, just a compatibility check that can be bypassed.

looks like more older CPUs (certain old ARM processors included) won't be able to upgrade to 24H2 as well

First-generation Windows on ARM PCs will not be able to run Windows 11 24H2

The kernel now excludes any chip sans the required set instruction.

Porting the 23H2 kernel into 24H2 will probably leave the OS in a broken state.

Either upgrade your hardware or stay on 23H2 or move to Linux.

Hi there

Still B/S

try dism /Apply-Image and then re-install the bootloader via bcdboot.

Cheers

24H2 will not boot without this CPU instruction, it's been mentioned here a few times.

Yep... I tried replacing some files between 23H2 to 24H2 but no success so we are stuck

In worst case I will buy a refurbished laptop which has the PopCnt instruction and give my test laptop to a friend or relative with Windows 11 23H2.

I mean Microsoft will not stop updating that build for awhile so

I’m running a 4790K, I installed it on my PC and it works great, of course I haven’t installed any apps on it just browsers.

This is a 4th generation Intel CPU which has the PopCnt instruction and is compatible. You only need to bypass compatibility check for the general Windows 11 hardware requirements (CPU, RAM, TMP 2.0, UEFI, Secure Boot).
