Z440 and similar workstations: Windows 11 prospects NOW?

[wny2016]

I gather from the basic Microsoft Windows 11 hardware requirements that a Z440 running a Xeon 1630 v4 isn't officially "supported" with Windows 11.

As I understand it, there are 2 basic problems: TPM version and the CPU itself. Upgrading factory TPM 1.2 to 2.0 is easily accomplished via HP software tools. 

I am beginning to see a LOT of Z440s on the second hand market being sold with Windows 11 Pro installed, same basic CPUs as factory installed. I know how to get around the hardware checks to actually install Windows 11 on a Z440, but as I understand it from previous posts on this board, the resultant Windows 11 will then fail to update properly down the road. A check of potential CPU upgrades show nothing that is Windows 11 compatible. What's going on here?

Has anything changed re: potential Windows 11 installs on these machines?

Review this post from just now for info on my "hybrid method" of upgrading from W10 to W11.... HERE .

I can do that upgrade on any HP ZX40 workstation regardless of processor or TPM etc. except I cannot do that yet with a ZX40 running from a HP Z Turbo Drive. Instead I use a SSD in our ZX40 workstations to successfully accomplish that upgrade. I can get a ZTD working fine in a ZX40 under W10Pro64 but have no luck in doing the upgrade to W11 if the boot drive is a ZTD.

Yes, HP might pull the rug out from under us some day, but just maybe they are finding good information at no cost by those of us doing these experiments "out in the wild". Our friends DGroves and Paul Tikkanen also have posted here about a method using Rufus... search those posts out. Both are highly trusted.

For reference, the official release date of "Moment 2" for W11Pro64 version 22H2 was just yesterday and I've got all my home workstations from Z400 v2 up to Z640 v2 upgraded to that now, no problems at all.

note that while the z440/z840/z640 systems TPM can be upgraded from v1.2 to the win 11 supported v2.0 nothing can be done on the CPU front as the motherboards chipset "ONLY" supports v3/4 Xeons in the  e5-16xx/e5-26xx line so this series of workstations will never be officially win 11 compatible with the MS hardware requirements hence the need to modify the win 11 installers to bypass the CPU/TPM checks

systems using 3rd party methods to bypass the hardware requirements of windows 11 upgrades/clean installs currently and for the foreseeable future will receive MS win 11 updates the same way a win 11 hardware compatible system will
