     Hello Welcome to my page, thanks for checking it out. I am an ethical computer hacker, I hack purely to gain knowledge in the field. Also I Have repaired many computers.

     Even some that people have given up on, the kind that sit in the corner of the room for 14 years untouched. Sometimes they need a Hard Drive, other times, they just need some new Ram, a new Bios Battery, or maybe they just need a re-installation of the Operating System.

     When I was young I watched "Buffy the Vampire Slayer" tv series, became obsessed with "Willow" from the tv series, who was a computer hacker who helped save the world. Since then, I have dedicated myself to learning many ways to hack computers.

     Now I can hack Windows Xp, Windows 7, Windows Vista, Windows 8, Windows 10, and some Linux Operating Systems.

     I also have learned how to do "Data-Recovery" That means that I can recover some files that has been deleted by the User. I can also Recover some files from a "Formatted Drive".

     I use this skill to help people recover files from their computers, people that thought their files were lost forever. I can also type very fast, I have an Average W.P.M. of 108/125 Words Per Minute. I Peak out at over 120 W.P.M. Did You know that the speed of 120 W.P.M. is within the top 1% of Typists in the world? That means once you reach this speed less than 1 out of every 100 Typists will be able to match your speed.

     This is very useful while using the Command Prompt, or Linux Terminal, and while Creating Tutorials or passing on my knowledge, this means that my Tutorials Speed will be very fast. Also I believe in teaching people the correct way, so I teach in a manner where once you learn how to use the Command Prompt, you will be able to use it in in all versions of Windows from xp/10, instead of just focusing on Windows 10 Command Prompt, which is the easiest to use.
