Yeah. I know of those bootdisk stuffs that finds the passwords. And that needs to be run using floppydrive or cd-rom drive or others. So, I can just take those stuffs out of pc, then they can't do anything using it, right? Since they don't have building computer skills. And all of the sites that you guys recommanded me, I love them all!!!!!!!! I will use all of them at once, hahaha.
