I would guess you are not talking about problems using your own PC.
I would guess you are talking about using someone else's PC and there are things they don't want you to do with it.
I''d guess that, because you don't have much (if any) integrity and you can't be trusted to do as you are asked, the person to whom the PC belongs has blocked the places he doesn't want you to go.
I'd guess that you are talking about a PC belonging to your school.
You could use the time at school to learn how to express yourself in English, especially with correct grammar.
If you want something to do on a PC at school, you could set out to learn just how much damage you can do to a PC by being stupid enough to try and bypass security measures.
You could also find out just how much pain and hard work goes into clearing up the mess people do get into.
One machine I cleared out had nearly 100 separate problems - and we are talking viruses, rootkits and trojans, not talking tracking cookies.
If, on the merits of your education, you do manage to get a job better than a shelf filler and you have the use of a company's PC, trying anything as idiotic as getting past security could easily be grounds for instant dismissal.
