Windows based systems have a structured database that stores various configuration settings and other saved options for the operating system called the Windows Registry.
It contains all the settings for the various low-level system components, such as COM components, in addition to all information necessary for applications running on Windows platforms.
The registry is also used to access a number of different counters used by computer programs in profiling system performance.
When a software installation program is run on the system, the system makes a registry entry for a software application for all its configuration settings and options.
Whenever a software application is loaded or run on the system, the registry database is accessed to acquire the configuration settings and options for the software application.
Why do we need registry cleaners? Most registry cleaners use a high-performance detection algorithm to identify missing and invalid references in the Windows registry and delete them.
Improper Uninstallation If your software wasn't correctly uninstalled, you might have to delete entries in the registry editor manually to make sure that the system performs properly.
Otherwise, the system will throw up nasty error messages and might not perform at the optimized level.
Windows usually has a default registry editor called "regedit" installed in the system for this purpose.
However, the interface is not all that user-friendly and a beginner might not be able to delete all associated keys properly.
Spyware There is another problem that requires a registry database clean-up.
Malware, spyware, and scareware will not uninstall properly unless the registry entries are deleted permanently.
So, to clean up your system properly, you need to install a registry cleaner for the system.
System Performance A third reason for buying a registry cleaner is to improve system performance.
The registry database may have a couple of software keys that relate to software that are no longer in use.
The registry cleaner removes the keys that are no longer in use and helps improve system performance.
Corrupt Hardware Drivers A fourth reason may be that you need to delete entries for corrupt or missing hardware drivers.
The registry cleaner will help you clean out missing or invalid entries in the registry database.
