I hope that the following article will help you to better understand this topic.

Windows registry is the main record or folder that all advanced Windows operating systems can use. Windows registry holds the information that is necessary for the operating system to work in a sufficient way.

All Windows registry holds a wealth of information about our computers, which is why we constantly find that after using the PC for a short duration of time, it no longer works the way it used to be. This is due in part to invalid or useless entries that exist in our system registry, which might exist because of a software we are no longer using or software that was not properly removed or un- installed. By erasing all those invalid entries we can get a significant boost of our computer’s performance.

Each time when I use my computer, Windows keep updating the registry data with the new-found information which ensures the smooth 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. Usually this is not what happens. As a rule of thumb programs leave behind them a good number of traces and entries after being un-installed. This could decelerate down the system by a great way. A registry cleaner scans the registry and finds out all the damaged links and unneeded entries and deletes them. By this Windows can be accelerated to a great extent.

A great number of Registry Cleaner Software is available on the Internet and many of this 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.

We can obtain several of the most common registry cleaner software in the market Here ,

and most of them provide a free trial period and free scanning of your PC.
