Registry Cleaner program

The Windows registry is a directory that stores settings and options for the operating system Microsoft Windows 32-bit, 64 bit and Windows Mobile. It contains information and settings for all hardware, operating system software, most non-operating system software, users, preferences of the PC, etc. Whenever a user makes changes to settings control panel, file associations, system policies or installed software, the changes are reflected and stored in the registry. The registry also provides a window into the operation of the kernel, exposing runtime information such as performance counters and hardware assets. This use of registry mechanism is conceptually similar to how sysfs and procfs expose runtime information through the file system (traditionally viewed as a place of permanent storage), although the information provided by each they differ greatly.
A registry cleaner is a program that scans the Windows registry and finds incorrect and obsolete entries.
Applications often create Registry entries for temporary data and links to other files, but never eliminate them. In addition, if the files are manually deleted by the user, log entries can point to files that do not exist. A registry cleaner can be part of a package of system utilities or a stand-alone program. A registry is designed to remove redundant or unwanted items from the Windows registry. The garbage collector attempts to remove unwanted or unneeded items in the registry.
Some uninstallers for Windows software does not completely eliminate all traces of the recording software. According to the technical details, these traces can interfere with performance or have other negative effects. Using a registry cleaner is one of the only ways to get rid of these bits. The registry cleaner scans the registry, and to choose the unnecessary parts and / or damaged and deletes / repairs.
Registry cleaners can often improve performance and reliability of computers by ridding the registry of unnecessary files and fragmented, which can greatly reduce the need for serious discussion.
Some registry cleaners offer backup and restore functions that allow the user to undo changes made by the registry cleaner if they are unwanted.
Some developers use the process of installing the software and hardware outdated or incorrect fail to remove all references to the application or when the equipment is installed or uninstalled.
Uninstall or change the software, hardware and drivers leaves a PC clean. Tickets will be left in the computer registry causing the PC to become unstable and corrupt. This results in sudden accidents, system failures and unknown error messages that can cause a serious delay in the performance of the computer.
When the software or hardware is uninstalled, it is likely that the remains are left on the hard disk or registry that clog the system. Without a good program to remove and fix these entries may be problems that cause immediate problems, including:
Corrupted entries left in the computer registry
Broken links and shortcuts
Program files, help files, fonts and configuration files
Applications that load when your PC starts
The PC quickly becomes bogged down causing frustratingly slow performance with random error messages and even system crashes.

Some of the benefits
Registry cleaners, or registry cleanup software, in some cases can improve performance and reliability of computers by ridding the registry of unnecessary files and fragmented, which can reduce the need for manual maintenance.
Due to the size of the registry, manually cleaning up debris and invalid entries would not be practical, cleaning products for the recording are essentially tools that automate the process of finding invalid entries and links broken in the registry and delete them.
Some registry cleaners offer backup and restore functions that allow the user to undo changes made by the registry cleaner if they are unwanted.
Some drawbacks
There are a number of problems with the concept of a registry cleaner. In particular, there is no reliable way of a program to see if a particular key is "trash" or not. Windows is closed source, so registry cleaner designers can not know with certainty whether a particular key is used by Windows or what detrimental effects removing it may have, which leads to examples of registry cleaners causing loss of functionality and, potentially, system instability.
In terms of performance, while on Windows 9x, it is possible that a very large registry can slow time to start the computer, the structure of disks in the file is completely different in the line of operating systems NT (like Windows XP and Vista). Slowdown due to swelling of the record is far less a problem in the modern versions of Windows. More important, however, the difference in speed due to using a registry cleaner is negligible: rarely take more than a few kilobytes of total size record. Any potential user of a registry cleaner should compensate probably negligible performance increase against a non-zero possibility of system instability.
