The operating system keeps in an information bank all the data related to the software and the hardware that is installed in the computer. In fewer words, every detail of the system configuration can be found in the Registry. This information bank represents the most important part of Windows and requires cleaning once in a while. A pc registry cleaner is a piece of software that performs a registry scan for redundant keys and eliminates them.

Cleaning the registry once in a while will improve considerably the performance of the computer. Windows 95 is the first version of the operating system to feature the System Registry. Previously, the data was kept in INI files that were found everywhere on the hard drive. Because of this fact, it was very hard to be informed of the configuration files. Thus was created the Windows Registry which cumulates all the data in a central information bank. The Registry stores in a single location all the configuration settings as well as the preferences of the users. It takes care of the startup settings and is aware of all the software that is installed at a certain moment in time.

If the system fails, the users are able to go back to the previous state of the Registry.
