Windows uses a system called the system registry. This is a central database that is used by all modern Windows platforms. This registry or central hierarchal database contains all the information that is required by the operating system to configure the system and make it operate efficiently. The operating system constantly refers to the registry for information. This may be several times a minute and the information sought may range from user profiles, which applications are installed on the machine, to what hardware is installed and which ports are registered and used for what service. The system registry was introduced in the late 1990's along with Windows ninety-five and replaced the older version of recording data in .INI files. The entire registry is composed of binary code and keeps on growing as the operating system adds entries to it. This slows down the system and it needs a registry cleaner to erase all the useless sentries to make the system more efficient.

What is the Registry?

As we use the computer the operating system keeps updating the registry with the new data it has to refer to for smooth operation. Let us take for example the simple file saving information, when we save a document the system has to record where the document has been saved and when it was saved also by which user. All this information is entered in the system registry. No consider how many times you save a document on the system. In addition to this consider how many sites you access on the Internet. Each time you open a site entries are made in the system registry. This makes the registry grow and slow down. Registry cleaners are programs that scan the registry and remove all the redundant entries. Registry Cleaners such as Windows registry cleaner is programmed to identify redundant entries and remove them. This makes the system faster.

So How Does The Registry Slow The System?

As the programs refer to the registry for information such as the location of a particular file or folder it has to start rummaging through the file from the beginning until it comes to the file entry it is looking for. All the entries are entered in hierarchical order so every time the programs refer to the registry they have to start from the beginning. They will also have to go through the broken links and useless entries, which number many thousands. This is why the registry slows the system. A registry cleaner like Win XP registry Cleaner scans the registry and identifies all the broken links and redundant entries that are entries not associated with any application, and removes them. This speeds the system up greatly.
