The Win 9x kernel was dumped after ME being the last of the Fat based versions. XP then incorporated the NT kernel into it while still retaining a degree of backward compatibility with Fat for use on older Fat16/32 networks.
The largest leap in the line was seen with the long gap between XP and Vista there. Once Vista was perceived as bloat wagon for desktops MS went to work on refining things there in order to see 7 come about while retaining Vista compatibility for most things especially existing device drivers.
The surprize here was seeing XP tuner card drivers work on the 64bit 7 while the Vista updated set for the same model fails every time showing a 3rd party problem not MS fault seen there. The one thing seen now in 7 will make XP users happy when upgrading and finding ways to see all their XP apps working on 7 but not Vista!
