Erasing unused disk space

ok, i got this computer from a friend who got a new one, and when i got on, it had 2 free gigs, and i guess it was set up to run and i didnt realise it and i have no idea how to use this thing, and now i only have 300free mb, my question is, how do i get my space back? i looked in the help section but i just dont understand how to use this, can someone help me please? i cant do anything on this now because i dont have the space to do so, so what do i do in order to get my space back??
