I deleted the windows.old and Win8 Pro installer after upgrading to Win8 Pro on Oct 26. It was talking so long to get my Win8 Pro backup disc that I went a head and ran the Win8 Pro installer and selected the option to have a backup Win8 Pro disc created. But now that my backup disc came in the mail I no longer need to do that. I can't seem to find a way to get rid of the Win8 Pro installer off my hard drive.
I suggest you delete some of your 'collection', or move data off that very full hdd. You can run disk cleanup, but it won't be a considerable amount as logs and temp files will be created again.
It's hard to fill a 2TB drive with non-copyrighted material, and if these files are actually important and not just downloaded copyrighted material you will want to make sure you have a backup of them anyway in the event of an drive failure.
