Update: Windows 11 25H2 (9.15.25)
turns out the Install.ESD file from 25H2 Win 11 DVD.iso is 5.1GB.
this was a problem to copy to USB as it is FAT 32.
solution:
delete install.ESD from USB.
copy the rest files to C: folder 25H2 (about 690 MB, 85 folders)
in disk management format USB to NTFS
when done copy back all the files in folder 25H2
then copy install.ESD to sources folder
Works. Installing on Ryzen 5 1600 PC. super cool way again.

internet has at least two widely quoted ways:
https://www.tomshardware.com/how-to/bypass-windows-11-tpm-requirement
SHIFT + F10 to open the Command Prompt. and launch registry editor during Win 11 install
Rufus to create a modified Win 11 installation media USB

appraiserres.dll file.....
What is this file for?This is the file that checks for Windows 11 compatibility (secure boot, TPM, CPU, etc.) when trying to install Windows 11. When deleted all compatibility checks are skipped.

Yes, there are many different ways. If you are system builders, just need two. One to be used with unsupported systems and one for supported systems, including soft floor.
Actually, many systems that have lower than 8th gen CPU are supporting installation without bypass. As long as the systems have UEFI, Secure Boot and TPM enabled. Haswell, 4th gen and up. Anything lower will need bypass or won't work due to new requirements for CPU.

1. "System Builder" are working this far back in time/tech ? Really ? Can you maybe catch-up to at least 7-years ago?
2. They are stopping you for a reason. Since they stopped-us at 8th gen (i5-8500, i7-8700, etc.) not sure I would go much lower that 7th-Gen (as long as everything else passes like TPM-2.0).

I get it, and I suppose it's fine if you are just playing games on it, or testing hardware.
But since this is the Optiplex forum, there are likely some business people here (who need to do real-work on their computers). Maybe Accounting, Payroll, Security, or other important things. They are looking for real, viable solutions.
I like your attitude, but I'm no "yes man". I'm just try to help and I'm gonna tell you like I see it. Keep up the good work buddy...

Will this upgrade my current install or over write it? I’m going to backup files, but it would be nice not to have to reinstall.
