I suggest you all look at reg cleaner
This program can delete all trace of program unlike add/remove programs.
It it a lot better than trying to use reg edit.
I guess it’s as old as Rome, lol !
very, very nice program I might add. clean, fast and easy to use with a zillion features!!! and a note, for xp users, regcleaner by microsoft will not work. go to the link 'bove.
