re-installing windows without reformatting

i have windows 98 first edition installed on a computer. i am wondering, if i
use the setup disk to reinstall the system, in dos, after it has installed
itself again, will i lose any customizations to my old system?

specifically, i am wondering if i will lose a desktop background image,
system drivers for installed hardware, etc. i dont want to have to reinstall
drivers for my hardware, or reinstall other software. i just want setup to
replace some corrupted files, and be able to find my personal files still in
their same place. can i do that, by running windows setup in dos, without
losing the items ive mentioned here? i just want to replace windows files,
not my own created files and installed drivers.

thank you
