It was mostly a side attraction while we played Smash Bros or whatnot. But the best part is watching a super drunk person trying to install windows. It was hilarious.

The media I copied from took up 28x 3.5" HD floppy disks. It's possible they were copied from what was originally a CD-ROM. I don't remember clearly anymore.
Note: I'm not trying to refute or correct your 13-disk figure, which was clearly a different installation set, and likely original Windows 95 rather than my OSR2, which came out around 1997.

Now I know why.
Edit: just checked in Google. Win95 was just 13 floppies. But you had MS Office and other software that was additional floppies to install.
