I create a question in [Windows Server forum](Question, Windows Server 2022 21H2 after trying to install 2022-07 KB5015827 CU get BSOD on VMware, ...) too.
Got exactly the same error! Praying there's a VMWkstn patch or something very soon
How to inform VMWare stuff about this bug?
Just FYI - Windows Server 2022 is not listed as a supported guest operating system for Workstation in VMware's compatibility lists, only ESXi.
Informing VMware staff about the "bug" would require you to open a support case with them. VMware employees sometimes can be seen in this forum, it's not part of their official duties - meaning that anything noted here is not guaranteed to be seen or addressed by VMware.
That being said, maybe some of the more experienced users here might be able to offer some advice.
Thoughts I have: What hardware are you running Workstation on, and does its CPU meet Microsoft requirements for Windows Server 2022? https://docs.microsoft.com/en-us/windows-server/get-started/hardware-requirements If you have a working Windows Server VM, have you tried running the Sysinternals Coreinfo utility to see what is says?
Also see https://kb.vmware.com/s/article/84239, which implies that you should be setting your virtual machine operating system type to Windows Server 2019, or Windows Server 2016 or later.
Out of curiosity what is shown in the Windows Server 2022 Event Viewer for this action.
I've check the Microsoft Update Catalogue and can find no refer to KB50145827, are you able to provide more detail on this.

I have just installed a standalone 2022-07 KB5015827 onto a virtual Windows Server 2022 with absolutely no issues [VMware Workstation Pro]. Therefore I suspect that what @Technogeezer alluded to, to be the case, that either its a configuration issue, previous patch conflict or a hardware issue.
So as suggested, take a look at your Event Viewer.
That (KB5015827) is listed as a security update.
I just tried to replicate the error.
1. Installed the 2022 server, with desktop (as a 2019 server). UEFI but no secure boot.
2. Installed all updates(including the above). No errors
3. Installed VMware tools. So far so good.
My processor is a Xeon W- 2255 in Dell Precision workstation. My host is Linux Debian, WS is 16.2.3.
what is your processor model?
Same here with VMware Workstation 16.2.3-19376536 : after this upgrade, Windows server 2022 crashs with this error "Unsupported Processor". Current workaround is to decrease the number of CPU/cores to 1. After this modification, WS start correctly and, if needed, update could be removed.
My hardware : i7 1185G7 @3Ghz + 16 Gb RAM (running Windows 11 Pro/21H2)
Hope this reply is helpful 😉
Thanks Louis! Decreasing to a single CPU / single core worked like a charm, you're a lifesaver!
Then removed July CU KB5015827, upped the cores back to 2 and voila!
Hopefully support for 2022 catches up on VMW.
Interesting catch. Here it is working with 2 processors and 2 cores from the get go. No crash, even with update.
I have a virtual machine running Microsoft Windows Server 2022 configured with 8 vCPUs, with all updates applied, including the offending one, I had no problems whatsoever. The host machine is quite old, run with Microsoft Windows 10 professional with all updates available to date, the same applies to the VMware Workstation pro product, has an Intel XEON E5-2690V3 processor installed.
Then I have another virtual machine running Microsoft Windows Server 2022 configured with 6 vCPUs with all updates applied, including the offending one, I had no problems whatsoever. The host machine run with Microsoft Windows 11 professional with all updates available to date, the same applies to the VMware Workstation pro product and is more recent, has an Intel core I7-10700 processor installed.
In both my host machines no component related to HYPER-V is active nor any energy saving mechanism. I use those virtual machines to test updates released from time to time by Microsoft.
Did any one test this bug with VMware Workstation 16.2.4 Pro Build 20089737?
No update ... BSOD again (same error unsupported processor) if I increase the number of CPUs with the latest VMware workstation version.
Just a heads up that this is something we're aware of and are working on.
Seems like a bug in the Windows Hypervisor Platform that we use (as the issue doesn't seem to persist when using our 'VMM', it only happens when we're using the WHP via our 'ULM', but we're trying to work around it.
Curious to know if there is an estimated timeline on a fix. We are running Windows Server 2022 in VMWare Workstation to perform application tests and the single core workaround is really bogging things down, and sometimes leading to crashes. Unfortunately we can't revert the Windows update that led to this.
Got the same issue.
only work around was decrease to 1 core, thanks
I don't know if it's an option for you but I run VMWare Workstation in Ubuntu and don't have the issue. It's a duel boot system and when I boot into Windows 11 I have the issue but in Ubuntu I don't.
Using an ubuntu host is probably more like using a windows host with `bcdedit /set hypervisorlaunchtype off` - you are using VMware's own VMM, rather than the ULM that interfaces with Microsoft's windows hypervisor platform. But then one can't run other things like docker, Device/Crendential Guard, etc that also use HyperV alongside of VMware anymore...
Hopefully this all stuff @Mikero has already found, but just in case not: I found https://twitter.com/XenoPanther/status/1561366066877562885, which referenced https://betawiki.net/wiki/Windows_11_build_25179#Boot_environment. Which seems like it might have some relevant clues about what changed; the timing is right, and the description feels like the sort of things VMware's ULM might be invovled in...
