No floppy or CD? You were just asking for trouble then IMHO. It was common to have to reinstall windows every 6-9 months in the win9x days. That didn't even really work for ME, but by then win2000 came in to save the day. Software was primarily distributed on CD those days, being without a CD drive must have been a huge hardship.
I vividly remember having to reinstall Windows also in the XP days at least once a year due to malware or due to anti-malware software slowly strangling the OS.
