Hacking is nothing more than testing things or systems to see "What Else" those systems or things can do or for discovery. What YOU are asking is info on simply breaking into someone's computer without their permission. I DO NOT RECOMMEND IT. With that said, I offer these small steps to get you started for educational purposes only! 1. Try going here: http://www.microsoft.com/en-us/download/details.aspx?id=856 2. If you can get your person of interest's IP address, you can use that to get in. No big deal. I suggest you practice with your little sister's computer or someone you know is not going to knock you out when they find out you have been sniffing around with their stuff. NOTE: this is not EVERYTHING you will need but poking around with this should enlighten you a little. 3. WARNING!! Just remember that karma is a beautiful thing. Good luck.
