It sounds funny that something with the word killer in it would be so good. Error Killer is one such product that is there to help us with these problems that are giving our registries a hard time running. We can all use the error product at some point. Keeping a clean running PC will be paramount to being able to perform at the best of our abilities and to discover that we really can do the things that we need to do without being slow because there are things there that do not belong there at all. This is good.
