Windows 7 consuming 50gb harddrive space

win7 takes up ~20GB of space, the rest of it is junk loaded by the manufacturer; most of which can be taken off. Do not remove anything relating to hardware (like keyboard, sound, graphics, or camera software), but all the crap backup utilities, toolbars, 'free' (lol) antivirus, and other things can (and perhaps should) be removed. After removing a bunch of software then force Windows to defrag.
