I had all the builds back to 98xx or 99XX, but all those pre-TP1 builds were on discs. I think I might have thrown them away, since I had burned them myself. I mad that decision when I finally figured out that I had a digital entitlement license attached to my Micro$oft account.
In addition, I had .ISOs of all the subsequent builds, but after I came back in August to grab the updated ESD2ISO tool from @Kari's tutorial, having realized that anything I had made since around AU was useless (which I figured out the hard way, trying to get the most recent IP build to boot in August lol), I made the decision to get rid of the entire store of .ISOs (>250 GB!), seeing as I would never use any of the previous IP builds again. So, I deleted all of them.
I then used HeiDoc's ISO down loader utility to grab the major releases, plus IP build 14965, and I did use the updated ESD2ISO tool to make an .ISO of 14971, but my storage drive is still 200 GB lighter
In my "Museum" I have iso of every build since day one. Some of first ones were downloads but rest are made out of install.esd.
Some of them lying around but mostly trashed. Can't see the point. I do keep my copy of Windows 2000 - great OS. I'd probably would still be using except its limited to 127GB hard disks.
