Try downloading programs like registry cleaners. (CCleaner or Advanced system care both are free) Run windows defragmenter. And another feature with ccleaner is clearing your cookies from your internet cache. First time I did it I got about 12 gigs back.

Ccleaner scan and defrag your hard drive should be the first steps. Also you could remove some programs from "start on startup" list.
