A Registry Cleaner is a specialized software tool used to safely clean out and repair the Windows Registry. The Windows Registry is a database which stores configuration settings for all hardware, selected system options, memory setup and software installed on your computer. This includes user preferences, settings and licence information. Manually editing the registry is extremely dangerous for your computer's operating system.
However, problems can also occur if the registry is not regularly maintained. If you don't fix registry problems as they arise or don't try to prevent them from occurring at all, then your computer system may begin experiencing system crashes, stalls or slower operating speeds. If you place high importance on fixing registry problems and preventing system crashes you'll end up with greatly improved system stability and operating speeds.
The Windows Add/Remove Programs utility and even official software uninstallers do not thoroughly clean your registry entries. A registry cleaner is a tool that allows you to get rid of troublesome and obsolete registry entries created by software and drivers that were not properly uninstalled in the past. It does not require any technical expertise to use it so don't be concerned about any limitation in computing knowledge.
As well as fixing registry problems, an even bigger advantage of having a good quality registry cleaning tool is that it can prevent problems from occurring in the first place. It will help you to repair and prevent many types of computer errors including ActiveX, DLL and runtime errors. Regardless of how old your computer system is or how it's used, there are many good reasons for cleaning an error-prone registry.
Some good reasons to clean your registry:
you frequently install and uninstall programs
you uninstalled programs that were never completely uninstalled
you have Spyware or Adware programs that you can't uninstall
you have uninstalled hardware
you have unused drivers on your system
With so many changes occurring over time through the normal use of your computer, your registry can become filled with errors and obsolete entries. Whenever you remove programs, it's highly probable that not all the components are completely removed from your hard drive or registry. If your registry is not properly cleaned of these obsolete entries and errors you'll be left with ongoing system problems as your computer attempts to process invalid instructions.
A good quality registry cleaner should also be able to detect:
Missing startup programs
Missing file associations
Invalid application paths
Invalid device drivers
Missing help files
Missing DLL files
Missing system fonts
