Using a registry cleaner is a somewhat controversial topic within the computing world and so the purpose of this article is to provide the user with an overview of what a registry cleaner is, why it is used.

Computers are not static entities, but are very transient in that they have to deal and contend with a significant amount of data and information with the passage of time, which is stored within the registry of the computer.

The registry is little more than a rather large database in which crucial information is stored and so details on the software currently installed on the computer, as well as information about the hardware peripherals associated to the computer. The registry is in some regards very similar to a cash flow or balance sheet for a business in that it will show all of the various “transactions” that are carried out within the computer, which will include the installation, removal and editing of software and hardware. Whenever there is a change in the computer, any change at all, a record of that is then kept within the registry by means of a “registry key.”

Usually, whenever a key is no longer useful or required by the computer (for example where the software application associated with a particular key has been removed) the key will then be automatically removed from the registry as a matter of course. This is a necessary safety mechanism because otherwise the registry would end up being totally overwhelmed with the sheer volume of invalid entries which are contained within it. However, there are and will be times when this safety mechanism is not properly satisfied and so the keys are not properly removed or worse yet, not removed at all.

A single registry key (or group of keys) can be used to control and manipulate several applications meaning that if the key for one application is corrupted then the rest are tainted too. With the passage of time these registry errors may then build up and cause a major amount of damage to the various system processes.

If you download a lot of material from the internet, make sure that you always scan it with a reliable anti-virus program before actually installing it to your machine. These programs are especially worrisome because they will deliberately insert and install embedded values into the registry which are extremely difficult to remove and which cannot be removed by manual means.

A registry cleaner program is used in an attempt to optimize the registry database by carefully removing obsolete and redundant values whilst at the same time keeping required registry keys safe. There is always a risk of major harm in the case of a registry cleaner that the registry keys are affected wrongly meaning that system instability is caused. Therefore, make sure that you only ever use a registry cleaner program which you know is genuine and which has been verified as being safe.

It is also extremely important that when you download a registry cleaner that it is actually compatible with the operating system that you have currently installed on your PC, and this is because different operating systems use different systems for storing, accessing and editing information in the registry. If you use a registry cleaner program which is incompatible with the operating system you have installed then you run the very real risk of creating more errors than you actually started with!

This is an easily prevented problem so make sure that you do not add to your troubles by using a lame duck registry cleaner program.
