The days of OSR releases...
I was working for a MS disti back in the day when 98 was released and remember it well!
I'd spent the previous month debugging their OEM Pre-Install Routine, otherwise known as the OPK installer; as the MS instructions simply didn't work! For every 5 copies of 98 we sold, we sent out my hand typed *extra* instructions, and never, ever, had an OEM system builder phone up asking how to get it working (unlike our competitors).
((I might have made a bit of fuss about this on MS's OEM forums on their fairly new website, and might have had an email from a certain S.Ballmer basically telling me to STFU))
Win95 had 15 seperate CD releases; the best of which was the penultimate OSR2.1 (OSR2.5 introduced USB support and was as stable as a chocolate teapot). Win98 had 3 releases from memory; the best (for overall stability in our labs) being the initial OSR1; 98SE was OSR2 and was a piece of crap; OSR2.1 was much, much better and was what should have been released to the public (but as was MS's way then, never was!)
