first of all incase u want to change any setting in a linux os...generally it asks for the admin user id and pass without which u cant get thru..... moreover noone tries to hack into linux...

they will not get anywhere by doing that..... all the imp stuff is stuffed into the windows......imp files like animations, 3d characters, music editors, passwords,GAMES etc....
NO HARM MEANT WHATSOEVER FOR LINUX THOUGH......
