I am always trying to get rid of any files that I do not use or are obsolite.So I keep downloading Maintaince programs to try to free up memory and see if I can run faster and smoother. Now I am wondering because of all these programs if maybe I'm slowing down mu computer or if I need all these programs to maintain my computer.Here is a list of what I have. I will take it for granted you will know what each are for. If not I can tell you later.Smart Fix.Crap Catcher,Dr. System,Mr. Clean,Mpower, Windows Washer,Heat protect,Spy Sweeper,Registry Lite,Tweek-All 3,and a accelerater program fromm my ISP AT&T.Maybe you can suggest some free maintaince programs that will do the same with less. I appreciate any help or input you can share with me.Thank You
