<waves hand> I use System Mechanic 5 I think. In the past I used it to defrag/free the ram before racing when I had only 512 mb. Also I would drop down to 1 mb free when I surfed too much with Windows 98 installed. I have XP and a gig now so... I also use it for the optimized defrag of the harddrive, mess with windows settings, the reg. scanner, and pretty much all the other utilities.
