hp z440 workstation, intel xeon e5-1650 v3.
Purchased with Windows 11 Pro installed. Fine thru the Oct 2024 update. Now the latest update/fix fails and states that my cpu is not supported.
Tried downloading directly from the Windows support site and installing the Windows 11, but it too fails.
Next step is to create a bootable usb and try to reinstall. Any input on if this will work? I'd hate to lose all my current installations/settings if this will not work.

The PC was never supported for W11.
None of the processors meet Microsoft's minimum W11 hardware requirements.
You will not find your PC"s processor on the list.

If you are still on W11 23H2, watch this video to upgrade to 24H2 which is the easiest way to do it in my opinion, and I have tried many different ways to do this during the last 3 years.
Skip the part where he tells you how to get the 24H2 insider preview ISO file.
Use the latest one from the Microsoft website link that I posted below the video link.

Download the W24H2 ISO file and use that (3rd option).
Download Windows 11 (microsoft.com)
You can download the free 7-Zip file utility from the link below. The top line is for 64 bit.
You'll have to repeat this procedure each October when Microsoft rolls out the new builds because a PC that does not meet Microsoft's minimum W11 hardware requirements will never automatically get the update to the next build.
Other than that, your PC will continue to get the monthly cumulative and other updates.
That's only a minor inconvenience to have continued OS support beyond October of 2025.

Yes, but there is now an easier way to do the in-place upgrade:
