@a06lp: 1) yes it speeds up AR6 (AR Speedup 1.28 does exactly the same) 2) this deletes delauft users coming with XP (remoteuser, help user, .NET user if installed) (note: here are German folder names involved) 3) This is because of different lnk- files that are in different folders (you could say: %currentuser%==%userprofile%) 4) yes, the links from the installation CD get copied that way 5) programs from the CD in "$OEM$\$Progs" get copied write protected! if you use a program from these folders, no changes you made will be saved, unless you turn off write protection!
