The difference for me is that the Killed by Microsoft has products I never used or cared about or I'm happy they killed them (looking at you Visual Sourcesafe) - cool site though - very interesting retrospective.
On the Microsoft campus, there is a building where the courtyard is tiled with commemorative "shipped in ..." plaques for various products. It has long since stopped being updated because there's simply no room for new ones. Walking there can be an interesting experience - very few people would recognize the majority of those product titles.
