Hi, @terekeme
Please see the new method I have used to in-place upgrade several HP and Dell business class notebook and desktop PC's to W11 22H2 that don't meet the hardware requirements.
Re: Issues upgrading to windows 11 - HP Support Community - 8517912
I had about an 80% success rate using this method.
If it doesn't work and you really want to install W11, you can use the bootable USB flash drive you made to clean install W11, and it should work just fine.
I had a 100% success rate with that on the PC's that wouldn't do an in-place upgrade.

Yes, and there is a specific "hybrid" method that allows you to go from W10Pro64 to W11Pro64 latest version. This then also gets W11 22H2 system and security updates automatically through Windows Update.
The post here you want to read is Solved: W11 Upgrade on Z420 Z620... easy - HP Support Community - 8474253 and you want to focus on my post on page 2 that has images included.
Currently the only HP workstation I've not been able to upgrade to W11 22H2 is a Z440 running on a Z Turbo Drive. I've pretty much realized that a nice SSD is good enough, which that same workstation runs W11 22H2 on just fine. The Z Turbo Drive needs a missing driver that the W11 install just does not provide (yet).

Paul,
Thanks for the update on your new method to use Rufus to get W11 22H2 to install on "unsupported" hardware. I want to try that on the Z440 with a Z Turbo Drive that I've not been able to upgrade yet.
In your linked post you seem to be describing only the in-place upgrade method where instead of booting from the Rufus USB drive one instead navigates to that USB drive from within W10, and then launch the Setup.exe from within the W11 22H2 installer software residing on the USB. If that fails you then advise to do a clean install but don't describe how with Rufus.
To do a clean install via Rufus do you simply boot from the Rufus drive and Rufus automatically harvests new drivers from the Microsoft archives? I'm hoping that is the case because those might work with a ZTD and W11. What I have on my W10 install that works with a ZTD does not translate over to function with a ZTD under W11 22H2.
Thanks much....

You're very welcome.
Yes, that is correct.
First, try the in-place upgrade by making the bootable USB installation flash drive using Rufus v3.18 that I attached in that discussion
The developers removed that nifty hack on the subsequent Rufus releases.
Open the file in Windows Explorer, double-click on the setup application and you're off to the races.
On the PC's where that method failed, it will progress to a certain point like 80% and without any notification or error codes, you are back at the W10 desktop.
Since you made the installer with the settings shown in my screenshot, all you need to do is to boot from it and it will bypass the hardware checks on a clean install as well and you should be able to clean install W11.
I couldn't update a dc7800 CMT or 8000 Elite CMT using the flash drive when doing the in-place upgrade but the clean install worked like a charm.
One caveat on the clean install...Microsoft now requires an active internet connection and a Microsoft account to continue setting up W11 after it is installed.
There isn't any way to bypass that as far as I know.
You can set up a local account on W10 and W11 21H2, but on 22H2 it is no longer possible.
So, I used my Microsoft account to set the PC up and then created a local account and deleted my Microsoft user account profile from the PC.
Since it would have been very difficult for me to connect these PC's to my router's ethernet port (I would have had to carry those beasts + a monitor up 2 flights of stairs to do that), the USB Wi-Fi adapter I use for my spare PC's had no native driver.
I had an old Intel 7265 AC PCIe x1 Wi-Fi adapter that I temporarily hooked up to those PC's one at a time and that worked fine since there are native drivers for that device.
That just took a few minutes to install, and I was able to complete the setup.
So, either way, if you want to install W11 22H2 on your PC it is doable.

I've done several z820's with custom win 11 22H2 install images (and win 10 22H2)
you can create yourself a z820 specific install image from the official Microsoft windows 11 image using NTLite (adds drivers to the MS image and removes the TPM2.0/CPU checks) then Rufus, which converts the updated win 11 folder into a bootable legacy MBR USB or ISO image
you can also PM me, and once you confirm to me you do own a z820 i can provide a custom pre made image that will install just like the Official HP images, without a serial ( requires the z820 to already have a win 7 digital license) or like normal retail win 11 installs that require a valid win 11serial
also my 22H2 install image removes the must be connected to the internet check by re adding the "I don't have Internet" option that previous pre win 11 builds offered allowing a local account to be created during windows setup

Paul and DGroves,
Thank you both for your high levels of expertise. I promise to update you both should I make a breakthrough getting the Z Turbo Drives (both Gen 1 and Gen2) working on my HP workstations, respectively. I mastered the ZTDs on W10, but so far cannot get them to boot on W11. Sigh.
However, a nice modern SATA III SSD is not a bad way to go to in order to work with W11 on these ZX20 and ZX40 workstations.

i've done a few z820 updates from previous win 10/win 11 builds to 22H2 that have the HP turbo Z AHCI cards installed as boot devices using my custom installers
PM me with the steps you are using for a update and i'll see if i can do a 22H2 installer customized to your needs
12-19-2022 06:48 AM
Absolutely.
I have W11 22H2 running just fine on an old HP dc7800 CMT business desktop that does not meet any of Microsoft's W11 hardware requirements.
It does not have a UEFI BIOS
Since it does not have a UEFI BIOS, it does not support secure boot
It only has a Pentium Core 2 Duo E8300 processor
It only has TPM version 1.2.
It works better on W11 than it did on W10.
