If drivers, applications or software were never removed from our computers and we never surfed the net, we would probably never need to clean our registries. Bear in mind spyware and malware are types of software and they are often being removed from our computers. This, in itself, means it is necessary to clean the registry often. Unfortunately, it is also true normal internet surfing will put a strain on a PC’s registry. So, if we don’t clean our registry, corruption will accumulate on our hard drives and the sad fact is, this will cause our computer’s performance to suffer greatly.
