You have System Restore.

what
anyway what i was meaning about the time machine was, the only way not using itunes would help me is if i never used itunes in the first place, and thus wouldn't open itunes, and thus wouldn't have a problem closing itunes. but in order to never have used itunes, i would have to time travel
and i want to close it because i'm not using it right now and i'm annoying about that, if i'm not using something i close it
