I think you're looking in the wrong location.
Locations of XP files like Documents & Settings, History and Temp Int Files are no longer in their usual locations. They are displayed when ‘hidden files’ are displayed but they are junctions, i.e. they are there for historical reasons so that old programs that would normally use them are redirected to the new Vista locations. The two examples above are now in \users\username\appdata\local\microsoft\windows .
Junctions can be recognised by having a little curly up arrow like a shortcut.
