Please explain to me why it would be of use to download the Piriform Defrag when Windows Vista 32 SP2 system comes with defragmenting. does this program do a much more thorough job. Just trying to understand. Thanks. I am having problems with system and just trying to learn as things come up. I see all of these different things advertised and am learning as I go. so thanks for any help to a newbie and definately a computer illiterate person. I do currently use CCCleaner which appears to have kept me out of "much" trouble
