um i think u mean u wanna remove 5 right? java u5 isnt affecting anything cuz its actually 6 running. sometimes the add/remove progs app doesnt work too well. it says i have 4 installs of c&c generals lol. just leave it there it wont do anything. if u want to check if it is still running for some odd reason then u can download regcleaner here:
click on the startup list tab and u'll see everything that is running when ur comp is started up. i actually dont have my java running unless something needs it and then it automatically loads once i do.
