I just took a quick look at that thread and there are posts from people with computers with much slower processors than in my old computers.roger_m, this is amazing, your installing Windows 10 on not one but three old laptops, and being successful at it. There's a thread on TenForums in Performance section titled: Let's Run Windows 10 on Really Old Hardware, do you follow that? Some installed Windows 10 earlier versions on single devices that were like 10 years old and were exuberant about that. But it seems you have many beaten by a few years and on more than one PLUS this is the bug-ridden 2004.
On some old systems, particularly with integrated graphics, in the past, Windows 8 ran a lot faster than Windows 10. It wasn't so much that Windows 10 itself was running slowly, but the UI was. For example, it would take a second or so for the Start Menu to open after pressing the Windows key. However, debloated versions of Windows 10 ran just as fast as Windows 8. But due to performance increases in recent builds of Windows 10, there is often not much difference in performance between Windows 8 and 10.I think those ancient computers will work far better on windows 7 or 8.1 x86 (reliable compact/lite versions if possible)
I'm using 8.1x64 on 1 of my first gen i3 desktop. It's even faster than itself on windows 7, after tweaks
I'm using Windows 10 1909 compact version. It's noticeably lighter than the original version without losing any feature
The problem with that, is that there are many computers that can run Windows 10, that will not be listed as being Windows 10 compatible by the manufacturers, due to not being tested. They will only test Windows 10 on a small range of models, when based on my experience with many computers, Windows 10 runs well on the majority of computers that came pre-installed with Windows 7.AFAIK many manufacturers have W10-compatibility lists for their products...
I'm facing the Intel display driver issue. This has been reported on the netIt would be interesting to hear if any of the people here filing the earlier 2004 feedback reports which said there had been no problems initially have since encountered any. Not to try to make anyone look silly, more to see if there is anything that can be seen as causing issues with hindsight over more than say a week.

For notebook which is NOTlisted in the Windows 10 upgrade list. Please aware the Windows 10 upgrade list only includes recommended MSI notebooks. You still can upgrade if a notebook passed "Get Windows 10 app", but there might be potential compatibility issues regardless of whether or not the device meets the minimum system specificationfor Windows 10.
What @roger_m said is pretty much accurate, there's no OEM that is going to test their entire stack of supported and unsupported products for Windows 10.MSI doesnt recommend upgrading laptops that are not listed in the official W10-compatibility list (from "Windows 10 Upgrade Information & Troubleshooting Guide" provided by MSI):
