While trying to fixup the vista problems Ive become aware that CCleaner isnt marking all of the famous index.dat files for deletion on a vista install. First it was RSS feeds, then more IE index.dats hidden away amongst the profile folders that are changed since XP. Looking into it more I infact have 7 index.dats on my windows boot partition and CCleaner only marks 3 of them for deletion on reboot.
