The closest to a total start from scratch came between Vista and 7 were things had to be reworked to make any progressive with Vista no longer having Fat support which had to be added back into 7 as opposed to XP's old install onto Fat32 or NTFS prmary options having carried Fat in from Legacy as well as having grabbed things from 2000! XP was mix mash of things tossed together by MS in hurry when ME flopped? or did it?
Vista still carried the Classic themes however showing how you still have some things that are built off of! Likewise 10 is taking up where 8, 8.1 where starting from but not where they should have been when seeing the general release. 10 still had to reflect back on 7 as well as other previous versions due to the demand for the return of the Start menu as well as still seeing other things carried over including IE and WMP. Those XP looking icons are still found in the system folders. Just right click on any shortcut to browse for a new icon and find plenty of XP looking items to choose from!
