If you want to keep them, I would burn all of them to CDR's. Then delete them. The pictures and the music at least. Take all of those off and see how much space you have left. If you just want to delete them, then that is really all you have to do, delete them. If you want to remove the games then I would uninstall them. Now if they are downloaded games...I don't know if you can burn those to CDR's or not. But then if they are downloaded games you could just download them again if you wish.

Frankly if there is just a whole lot of stuff on there that you really don't care about losing the easiest way, rather than uninstall it all is to do a full reformat and reload. IF you have all the disks that came with the computer, all the disks for the programs you DO wish to keep, then a reformat and reload should just take you a few hours. Once you reformat and reload with all the original disks then update and you are good to go with a fast computer pretty much restored to the way it was right out of the box.
