Clean install on HP Probook - Which ISO?

Hi @ all and big ups for the forum.
I have a HP Probook 450 G7 notebook which definetely needs a clean install, although it is currently running latest version 20H2.
I have checked with the HP cloud recovery service, the provided "recovery' media is just an bootable .ISO with Win version 2004. There is also an app for quick install of all the drivers and HP additional software which were actual as of June 2020. A 2004 complete driver pack (September 2020)as seen in the HP Image assistant availability matrix, while 20h2 is not supported like this yet.
I have also downloaded 20H2_v2 iso from MS as well as all the current 20h2/2004 drivers from HP website. Is there anything else on the image provided by HP except from the apps & drivers quick installers and activation details? Which one should I go ahead with?

Thanks for your comment.
The notebook had 2004 installed from MS iso as it was bought in June. Everything was going fine despite the endless 'quality'and driver updates. However since these new builds and updates started coming out in October it started losing its overall performance piece by piece. WU, MS Store and HP Support assistant istalling driver updates over each other, rubbish performance, various issues with the hdmi, wifi and audio outputs. Did a clean install with 20h2, the ISO file from Microsoft was titled 20h2 v2, installed latest drivers from HP, everything was fine for a week or so. Primary drive is a 256 GB NVMe M.2 Value SSD which was wiped prior install and sucessfully imaged on an external HDD several days after when it was ok. I have installed another SATA SSD for data anyway, so losing the current paritioning on the primary drive is not a issue. I have noticed that it starts losing performance as soon updates come in. WU, HP support and image assistants, MS Store.. all of there keep on reinstalling drivers and apps and the result is an endless loop which I suspect slows down the OS to the point that a simple reboot would require 5 minutes at least.
I was looking into this https://support.hp.com/gb-en/document/c05195282 and was wondering if the HP supplied Win 10 2004 Image would be better in terms of overall performance and driver/apps updates.

That's another story but I had a Dell back in the day.. Unless you went with installing all the bloatware, it was always better to had Win7 installed from the recovery dvds than from genuine untouched image.

I've always found HP software to be too intrusive. I would install vanilla Windows 10 from Microsoft's Media Creation Tool. Let it go through all updates. Then install only HP drivers needed for whatever hardware is left that needs drivers.

Please update your system specs. It will help us to help you.

What was the latest build that run without issues? 1909, 2004?
Why don't you install it and block the updates?

I've been running a HP laptop for 6 years with all the HP bumf still installed with no slowing down and not done a clean install yet on it. Makes me think you have another issue.

If you've never ran it with a vanilla Windows install, how do you know that the HP software is not slowing it down?

Okay, so I had some time today and applied the NVMe drive image with the 20H2 fresh install + drivers and limtied apps. Much to my surprise AOMEI Backupper did a great job. The PC had everything installed just to get going - a combo of WU and HP drivers and apps. So first thing I did was to get rid of HP support assistant and set MS store to complete manual update . Being offline I installed latest updates from HP Image Assistant which were out of date. At the same time tried to disable drivers through WU. No sign of the tons of Vendor software components as seen before. At the end applied the latest OS update to build 19042.685. Did a bit of cleaning after all of it and was surprised to see WU, delivery optimisantions and temp files eating 30+ Gigs of space. The notebook is running fine by now, even though not as quick as with the 2004. Not impressed with the typical Microsoft quality solution.. 2004 with 16Gigs of RAM was doing much better in the end than 20H2? with 32Gigs. Dunno who tests these new builds but it seems that all of these people are totally incompetent and the story goes the same like 20 years ago with the Win ME or big talk on the revolutunary XP update feature. So I hope that the system will not get clogged again quickly and HP will fully support the actual 20h2 version soon.
