The Registry is the heart and soul of any Windows system. Registry controls how your system appears and how it behaves. When you install an application, new entries will be created in Registry of your system. But, uninstallers of some software do not completely remove all traces of the software from the registry. It might be possible that these traces may interfere with performance of your computer.
This will significantly increase the Registry size and slow down your computer. Your Windows will take more time to load, search, and read data from the Registry. To keep your computer at top performance, it is recommended you periodically clean your Windows Registry.
A Registry Cleaner is a software utility that removes the redundant or unwanted items from the Windows registry. The registry cleaner scans the registry, and picks out the unnecessary entries and deletes/repairs them.
