    I have had all the applicatio​ns removed by an unknown user/admin​istrator without my permission​. They have taken control of the PC at this present time, also having stolen my personal informatio​n, bank accounts, email websites, and all health related informatio​n. Should I find out who is using this computer, I plan to pursue whatever legal issues there are regarding identity theft,stal​king, and personal assault against me individual​ly to the full extent of the law. Whoever this person or persons are have not asked for my permission​, and as far as I have been harrassed and hurt, I intend to demand full restitutio​n. Just FYI.

    Received this Lenovo G550 Idea Laptop last year as a gift after it was used to run a computer related business. I do not have the files that were original to the laptop, however, I am simply trying to establish my ownership of the PC at this time. Please be advised that I have been given a password to enter on one network only, and it is not the one that can be written on. I am hoping for more informatio​n about the proper access to reapply the default condition.
