Windows registry is the main record or folder that all advanced Windows operating systems can use. This registry contains all the information that is essential or needed by the operating system to make it function efficiently.

A lot of information about our computers are stored in Windows registry and this is why we always find that after using our PCs for a short span of time we discover that it does not work the way it used to be any more. This was due to invalid entries which can be found in our windows registry, that may be there because of a software which is no longer being used or because of a software that was not un-installed in a proper way. By ereasing all those invalid entries we can get a significant boost of our computer's performance.

Every time we use our computers Windows continues to update the registry with the new-found data which grantees the good performance of the operating system. Each time we install a new hardware or a new program, a group of new entries are added to the registries, which are unique and essential for this program or that hardware to function in a proper way. After uninstalling a program from our computers it is assumed that all the registry entries belonging to that program could be removed. However this is usually not the case. Generally programs leave a great number of traces and entries behind after they have been un-installed. This could lead-for a great exetend-to the deceleration of the operating system. A registry cleaner scans the registry and finds out all the damaged links and unneeded entries and deletes them. This can increase by a great way the speed of the operating system.

A great number of Registry Cleaner Software are available on the Internet and many of these software are free to download. All the registry cleaners  are sharing the following tasks, which are the scanning of the registry for old and useless data, fixing the registry by deleting the unneeded  redundant data and compressing the registry and backing up the old registry in case it needs to be reinstalled.
