School Network help

[Kai Gill]

So my school has very good IT administrators who are quick to spot any faults in their network. They prevent any other software from being installed and block most websites (especially yahoo answers because it's a "social network"). They block proxies almost instantly and even deleted chrome for us because people found ways through. They use wired Ethernet connection which aren't accessible to us otherwise i would connect it to my internet. Even the virtual machines had these restrictions and now they blocked the internet on them. CMD is also blocked as well as control panel and they killed our ability to adjust mouse cursor speeds like wtf. If anybody knows a way i could bypass these restrictions it would be much appreciated. The school runs on windows seven professional. Also please keep the responses semi reasonable because i can't exactly rip the hard drive out and re-format it!
