How to break \ change Administrator's Password?

I will speak the truth about it. I want to break the password of my schools security. I live in Pakistan and there is not so much security. The computer Administrator has set limits for users. On my stage I even can't

store a file in C or D drive, cannot install anything and cannot access User Accounts in Control Panel and my limit is the highest in Class 8. I just want to break the password and frighten him and show the security is nothing. If anybody helps me I will create my account on network and install games and create accounts on other computers for network gaming.

Can somebody help me.. PleaseHow to break \ change Administrator's Password?
