Because I don't want ANYONE accessing some stuff I have on there. AKA assignments that aren't exactly "educational" I have most of my PC research stored in a folder that has been restricted by me. However it is easy to open the folder should they figure out whats inside. If they knew everything I knew I would be in trouble for sure. A lot of the school laptops are not genuinely updated with genuine windows. They were running a trial and it ran out. Now a lot of them are crashing and one even spat a BIOS password at me. I bypassed it by resetting the CMOS. (This won't work in some laptops.) I got into a fair bit of trouble over that. Anyway they don't want me learning anymore about PC's because they are worried about what I could do if I got ****ed off and decided to wreak havoc. But I won't. That's what they don't understand. Anyway some body just get me something that works in an extremely restricted environment. Like a students permissions environment.
We can't help you bypass another organizations restrictions. They're there for a reason and without us knowing both sides of the story, there's no way for us to know who's telling the truth.
