Edcole1961: The numbers make sense if you know how Windows refers to itself internally, through version numbers. Leave out NT and 2000, because they were a different product from the home versions that the numbering comes from.
Windows 1.x, 2.x, 3.x
Windows 95 = Windows 4.0
Windows 98 = Windows 4.5
Windows ME = Windows 4.6
Windows XP = Windows 5.x
Windows Vista = Windows 6.x
