Cleaning the Windows registry is a popular and controversial topic. Many pundits tell you never to do it. When I wrote a book about Windows back in 1999, I dedicated most of one chapter to the topic. But today the pundits have a point. Most registry cleaning utilities do much more harm than good. I don’t recommend you clean your registry, per se, but I do recommend you maintain it.
I don’t want to dismiss the concept completely out of hand. There’s a difference between a bad idea and a bad implementation. Registry cleaning and maintenance is a victim of bad implementation. But that doesn’t mean it was a bad idea. So let’s talk about how to get the benefit while minimizing the drawbacks.
