Bypass Administrator Settings Win 2000/XP

Hi, I would like a neat little program that will bypass settings applied by the Administrator that locks down your pc so that you can load applications, access or save to certain folders etc. Basically I would like to be able to change any settings made by the administrator. Must work with windows 2000 & XP. There must also be an option to put the settings back to the original configuration set by the administrator. Any questions, please ask. Please bid for total amount not hourly rate. cheers
