At school pretty much everything is disabled for Students

We can't even right click
The main PC I use is Windows xp/95

I can't use Run or anything, is there a way I can gain right click permissions and shit without getting into the main PCs?
like notepad.bat or something

Also 99.999% of the web is blocked I want to get around this No proxy sites work.



I'll easily be seen inserting USB devices or disk and downloading would be a terrible option as well
