I have the same issue. I have built my own computer for the first time and installed windows 10 from USB as I did not want a CD drive.
I have a catch 22. I have no CD drive. I need to update drivers to be able to connect to the internet through Ethernet. how do I do that?
I have got an old computer I can take the CD drive out and install in the new one as a temp maybe as a last resort.
