i aggree with alittlebitnumb happyhacker.org has lots of info on where to start. and as a littlebitnumb said it is all legal so you can practice and practice with like the first part of it then move on to the second part etc. learn it all read it over and over again so you memorize all the most important stuff and when you have finished learning the windows stuff on happhacker start on the unix tutorails on happyhacker. unix if didnt all ready know is the back bone of the internet it is more advanced the windows and a lot more flexible it is all command line like dos you should start trying to proggrame to if you allready havent try a simple language to learn like python www.python.org you can dowload it at that link.when you feel you are getting comfotable proggraming in python *if you start that is* move on to C or C++ remember hacking is illeagal if you get caugh you can face a hefty fine and a prison sentance so if you wanna be a white hat as ppl put them go ahead but it isnt really hacking in to computers all the time it`s more like patching and finding vullnarabilities in systems and networks so if you think it is hacking in to computer`s sorry to have burst your bubble
