Man, someone would really have to have a lot of time to kill to want to sit around and install every version of Windows from 1.0 to whatever...
And also, thinking about that, if whoever was doing it was doing it *right* and matching a contemporary version of DOS to each Windows they install they'd have to at *minimum* reformat/repartition the disk... a bare minimum of twice... it depends, I suppose, on whether you were to let the person doing it get away with installing Windows 1.0 on a disk formatted with Compaq DOS 3.31, the first version of DOS that supported FAT16B's 2GB maximum partition size vs. previous versions' 32MB limit. The two *barely* overlapped each other as "current" products but I guess if you let that fly you could in theory go from 1.0 to XP on the same partition. But you'll still be boned when you get to Vista, which ain't fitting in 2GB period.
