Got Windows 11 installed on my "unsupported" machine.
I first got Win 11 working as a Virtual Machine using Virtualbox. That required me to edit the Registry to complete which wasn't hard, but I prefer to avoid RegEdit if I can. I ran like crap in the VM. Pretty much unusable. So I bought a new 1TB SSD and installed Win 11 on that (keeping my old drive with Win 10 on it in case Win 11 didn't work well).
I found a guide that will allow you to install the ISO to a USB drive and make the installer not check for the TPM chip that is required. I used this guide with Rufus. Piece of cake. No RegEdit this way.

I don't see why anything that worked on Windows 10 wouldn't work on Windows 11 as there isn't a huge change in the actual OS.
Liking it so far. I'm sure that, as with Windows 10, it will take a bit of time to find things again. I've found the search function in Windows 10 found what I was looking for most of the time.
So far things seem just as fast as Windows 10. FWIW, my machine has a Intel Core I5 6400T with 16GB of RAM. Graphics are pretty basic. Intel HD Graphics 530 integrated chip.
