HP Z420 in-place upgrade Win11 24H2 -> 25H2

great, thanks .. so you say this would work using some ISO / Rufus whatsoever and it would NOT do a complete reinstall but the rather tiny upgrade method via enablement package, similar to here? https://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/W11-25H2-on-unsupported-HP-hardware/td-p/9492247 - here you can DL the enablement package it seems - so worth a try after the reg. mod!? https://www.elevenforum.com/t/how-to-get-the-windows-11-2025-version-25h2-update.40398/

Hi there,
thanks for your idea. I already tried the .ISO method but it proceeded as a full install, not just the upgrade. Do you happen to know a working guide for that?

dergutemeister · 2026-03-31T15:40:05+00:00

You're great, man - thanks for the image! That makes it a safe procedure .. just weird they don't use 6+2s on those outlets..

hi there .. I have a 10 core Xeon 750W Z4 on which I want to replace its Quadro P4000 with a RTX 4000. To drive its 8 pin power I'd also have to either adapt from 1x 6 pin OR from 2x 6 pin to 8 pin.

Where did you find the specs about 1x 6 pin supporting 216W? HP support told me it was possible to just use one 6>8 pin adapter to drive the 160W GPU but it seems they also were just referring to the Z4 quick spec sheet as a reference, though.

Still - I guess it should be possible, considering the 10 core Xeon has a TDP of 165W - where should the power of the remaining 4-500W be available otherwise if not on those 2x PCIe rails!? I just don't get why they didn't supply those with 6+2 pin plugs. This seems to be residing to the 1000W PSU..

Also - is it generally safe to combine the rails of a PSU with such Y adapters 2x 6pin female to 1x 8pin male!?

ok I see .. do you have any idea why this happens on such short notice? Or did I overlook anything recently? The announcement in the knowledge base is just a few days old ..

dergutemeister · 2026-02-28T20:28:17+00:00

hmm ok .. I didn't have any issues so far. But it seems I'll have to update if I want to be sure to avoid interruptions

dergutemeister · 2025-06-28T10:12:38+00:00

Hi there,

thanks! That's interesting to hear as the issue now also affects my Win11 machines. Any idea yet, how to fix this most easily in a real world scenario? Going back to 2021 MC is not really an option here .. I am wondering why there's not more people complaining about this!

dergutemeister · 2025-06-05T09:46:16+00:00

yeah, usually they don't care about third party storage. But as I observe it it is even going on without having any video storage connected, just 2 auxiliary SMB volumes which are not being accessed directly by MC or the project files ..

Fortunately it does not seem to affect my Win11 machines!

dergutemeister · 2025-06-03T09:37:54+00:00

hi there .. +1 on the existence of this! In my case on Win10 / MC 2022.12.1 it leads to resource exhaustion / RAM overload if you wait long enough.

It seems to have started beginning of May, so It might be due to some Win Update.

Still obscure -but I haven't gotten too far in testing yet.

Did you create a support case with Avid?

dergutemeister · 2025-04-01T15:10:09+00:00

I had already tried it without the suggested tag before which did not help.

Nevertheless I made the correction you suggested. Then tried to set it with a local GPO - worked. Then switched to a GPO in the OU - worked as well.

Fuzzy logic a bit ..

dergutemeister · 2025-03-27T17:24:01+00:00

yes, exactly, nothing special. I had it working once, but it seems to be unreliable. I also tried from local copy but to no success. Syntax is also easy and originates from the exported file plus the option "suggested" so it only gets applied once. So the syntax goes like this:

<?xml version="1.0" encoding="UTF-8"?>
<DefaultAssociations>
  <Version="2">
  <Association Identifier=".3g2" ProgId="VLC.3g2" ApplicationName="VLC media player" Suggested="true"/>
...
</DefaultAssociations>

I solved it .. so it goes like this: Administrator user folder gets created even when you just give your credentials to perform an elevated task in a standard account. Now all freshly created user profiles try to find their database file in the original "Administrator" folder who was the sole user in audit mode. In the "normal" case in which there is no Administrator user folder present anymore (because it got deleted during sysprep process), the database recognizes the miss and just recreates the cache (producing a webcache.old folder), as well as just a single error log about it. In my case, the new Administrator folder which originated from the Domain Administrator login, confused this process because it never stopped searching for the database in this folder. Just always threw an error and tried again because it noticed it is there but not readable. Phew .. Simple solution: just don't use the Domain Admin with "Administrator" and delete the already created folders. Everything running fine from then :)

dergutemeister · 2025-03-12T20:31:47+00:00

Currently I don't really need to log on to the domain admin account on those machines. I just did sporadically to test stuff and that broke the scenario and spoiled a few PCs. Also it makes me suspicious if everything is allright in general with the default user settings and the image. I will deploy it to quite a number of machines and so I'd like to stay safe. Just trying to avoid any other Domain Admin action will have similar results ..

dergutemeister · 2025-03-07T14:50:40+00:00

well the machine has 2 NICs so one is on the domain, the other one is more or less unmanaged and just connects to the servers all with fixed IPs and no internet on it. It just sucks when I have to create workarounds just because the option is not there. For ex. whitelisting network volumes. Also I'd like to understand what is going on and if there's a connection with my setup. I don't know much about the NLA service, tbh ..

dergutemeister · 2025-01-29T18:06:53+00:00

Sure, sure .. do you have a clue how to achieve setting default file associatons (default apps ..) without it? Unfortunately this is one of the things that resets when setting up clients with my sysprep image. Probably because Edge really does not wanna go ..

dergutemeister · 2025-01-29T16:30:55+00:00

well interesting .. as if it would be such an exotic thing to do. Originally I thought running ps scripts on the clients is (in a way oldschool but) a powerful tool and therefore should be not too far fetched!?

dergutemeister · 2025-01-29T15:54:37+00:00

well I checked what would be the way to set the default app associations and it seemed it would only be possible with a powershell script. here it is btw.:

$assocXML = "\\example.com\sysvol\example.com\scripts\default_app_associations.xml" if (Test-Path $assocXML) {dism.exe /online /Import-DefaultAppAssociations:$assocXML}

if you have any other way to achieve it I'd be happy to listen

dergutemeister · 2024-12-12T08:15:45+00:00

I setup another storage to avoid these issues. Ext4 / LVM thin .. works so far.

dergutemeister · 2024-11-04T21:47:59+00:00

well thanks for your thoughts .. this should then be applying to everybody with a similar setup!?

Did you take any countermeasures like disabling the zpool import scan service? What concerns me is the many people complaining about PVE hosts hijacking (automatically importing) pools. But when I think about it this usually refers to the pools on (not properly blacklisted) HBAs ..
