Thanks! I wish I had this info for an old build.

Sidebar: Kind of silly how you and others are tripping over yourselves to include something against win11 while providing tech support. As if you'd be a pariah if you didn't include some disdain.

"Here's some win11 troubleshooting advice, not that I'd ever be caught using it! ;)"

Probably for the best -- using it without those hardware features is rough. I was using a Ryzen 1600AF -- which is odd because it's not on the list although it installs normally with no issue because it's really an underclocked Ryzen 2600 Zen+ chip. The Zen+ chips are on the support list but they lack some of the virtualization features in hardware. I was seeing a massive difference in performance when I toggled the security settings that used them. Sometimes 15-20% difference in games.

6th and 7th gen have firmware based TPM that Intel calls PTT. (Though whether it's available to configure in the BIOS depends on the manufacturer and sometimes the chipset.) But correct, it still needs a workaround because TPM isn't really the (only) thing it's checking for.
