007f:00000409 was the only one that wasn't English from another country, so I thought that it was for the US. I even tried removing the unattended file but still ran into the same error. So I've removed 007f:00000409 and some other things from the Preset, and added some things I'd forgotten about. Virtualbox to the rescue to find that out. Also, I've integrated those drivers before and it wasn't an issue. I went ahead and downloaded a new ISO with Rufus, loaded my preset (spent hours fixing things and resaving it ️), and created a new ISO. Went off without a hitch in my virtual testing.
I'm about to reinstall Windows 10 afresh since Hellbovine's Optimized Image Guide broke something in Windows explorer and maybe a couple of other things. Something in the registry files I'm just too dumb to suss out, so I couldn't figure out how to fix some of the choices he made. Though I am taking his advice to stick to Windows 10 21H2 as 22H2 just messed with things whch really frustrated me. I forget why I even moved to it to begin with last year. Something about "bug" fixes and "performance improvements", I think.
Maybe someday Windows 11 will get it together, like maybe after Microsoft FIRES its current development team. I've been awake too long, so I think I'm beginning to ramble.
Thanks for the help, everyone! Just for fun, I'm attaching my slightly better preset below.
