JFX, it WORKS!!! I'm very very very happy!!! Have a beer on me!!!
Well, you ARE patient, because you always respond to questions, and even though I've told you countless times to "shut me up" if you get bored, you never have. I really appreciate that!
Now I can go back to my preferred method of leaving the original wim files as original as I can (only add NetFX3, remove appx and let update), then in PESE I check which machine I'm on, mount the correct driver iso (if needed), then integrate drivers with WinNTSetup. Very nice and very clean.
I've learned a lot this week about DISM, so that's an added bonus.
Just wondering about one thing: why did the download fail? (See, I'm never satisfied...)
No kidding, you have my deepest respect, sir, and I wish I could buy you your preferred beverage right now. Cheers!!!
