After hardware installation, while you wait for updates to download or for applications to install/upgrade, you could watch your favorite series or some movie in a PiP window (Picture in Picture), so it gets much less boring.

Legacy MBR installation, no TPM, no Secure Boot, no WDDM 2.0 graphics drivers, no SSE4.2, cannot get more unsupported ;) This is only my test laptop. I had installed Windows 11 here before upgrading my main PC. For my main PC I use everyday see my 2nd system specs.
What I remember; I started with on old hardware (i7-6700K and Z170) with OEM RTM Windows 10 Version 1709. Kept updating throughout the time till Windows 11. Because it was free to upgrade I did that. Was sitting on 23H2 with my old system. Bought more recent hardware. (i7-12700KF and Z690) Used the 24H2 .ISO. It saw the change but asked if I was using new hardware. Yes. It installed it as normal. From there on upgraded to 25H2. Don't remember to typing long numbers or something like that. Had this once but that during the transition of XP to Windows 7. Had to call MS and type a long number to get activated. Today that is behind this. It's more based on your MS-account. (Have 5 VMWare machines "registered" MS sees they are all based on VMWare. They do not complain.) MS is not living of the licences anymore but from the data they collect from us. OEM or retail are 100% the same. Except with an OEM you don't get support. That's why the OEM is cheaper than Retail. Official an OEM comes from some PC builder like Lenovo, HP etc. but in reality they are also sold to customers.
I would recommend a new install. You can backup your data from your old system and restore your personal files on the C-drive where ever they are to any location on your new hardware. (Hasleo) Inside your current registry there is a lot of stuff pointing to the old hardware. Windows will adapt but you never know what else drags it along from your old hardware. A fresh and a new start. All you have to do is to install programs you are regular using. Have done that many times in the past. I think let's keep that program but after a while you haven't installed it yet..... If you are using an MS-account and are using OneDrive you don't need to restore these files. If you choose for it it will download it content onto your new system. Even Google (Chrome) lets restore your passwords and links. So your browser is up and running quick. (You can export (for safekeeping) and import them. Used this recently when I stepped over to Brave.) Edge does it also from a backup made from your old hardware.
Apart from the programs we are regularly using, we usually have twice as many we use occasionally but we want them installed. All of them assuming we have the respective keys and licences to reinstall. They not only require time to install, but also more time to configure the way we like them because the default configuration is not convenient. For a typical home PC with tens of applications to reinstall and limited free time this can take more than 2-3 days. So clean installation is not always the best choice. Yes, it might be a little faster than an old installation but I value my free time more than a small difference in speed which with an SSD is even smaller.
