For Nvidia, we only need to search one single file around those many,
usualy named Setup.exe Click to open and the program runs once for
instalation. The same for WLAN aplication, do you see any setup.exe for
it there?

I did OK with NVIDIA, but there's no .exe for wlan, only NTIDrvr.sys

I found an rtl85n86.sys which seems to be wireless realtek. But what to do
with an extension .sys ???

Thanks for your time !
