Beware of these
Yes, wizard57: "snake-oil" may well be the the proper term for them.
I wonder if there are benchmarks that show _any_ benefit of these utilities? Having read good reviews of CCleaner I had a go in XP with using the latest CCleaner available - using the default settings - and the result was very close to a disaster. Fortunately I had a backup of my registry and after a couple of hours with cold sweat on my forehead I was back in business. I really had trouble getting the computer boot up let alone run just about any executable.
Yes, the CCrap only did it once but that was more than enough for me. God only knows the damage it might have done had I not backed up the registry. As for the workstation it is still working perfectly after four years from this incidence. This experience answered the most important question there is: Why fix it if it is not really broken?
