If you can't find any way to suppress it, perhaps you could write a script using AutoHotkey or similar which interacts with the wizard. I'm not sure if they're special in some way that prevents AutoHotkey from interacting with them, but I doubt it, 9x isn't meant to be secure 😁

I couldn't find a build of AutoHotkey which worked on a clean install of Windows 95 RTM - the best I could find was something which needed some additional redistributable(s) installed - but I have my own build which works, and I can try to hurry up releasing it if you need it too. However, I imagine if you're trying to provide an easily usable Windows 9x, you're not using Windows 95 RTM without those libraries anyway 😁

Are you launching windows from DOS? How about run a batch script which checks your system and the driver directory, and then merges in reg files and places the files in the correct place, and then launch windows? Then it should never need to install drivers in windows.

You'll want to snapshot your registry and windows system files before and after driver installation doing it the correct way, and then export reg files with the differences and a copy of the driver files in your driver directory.
