WHAT IS REGISTRY?
Registry is a system-defined database which is used by an Operating System to store all the information needed to configure the Windows settings for 1 or more users, applications and hardware devices. Information contained in registry includes user's profiles, application installed on the computer, types of documents that are created, setting of properties sheet for each application folder and icon, existing hardware in the system, and all the ports that are being used.
WHY CLEANING THE REGISTRY IS IMPORTANT ?
When using the computer, users may have experienced quite a number of problems relating to registry issues that may result in severe consequences such as error messages pop-up, noticeably slow performance of a system or even system crash. The reasons leading to these problems, however, are mainly caused by missing or invalid registry key(s) from the Windows registry.
Usually, when any particular application is uninstalled from Windows, it is recommended that you should use Add or Remove Programs feature to proceed ( Start menu > Control Panel > Add or Remove Programs ) However, if you delete any program manually without using this function, you might mistakenly move away the registry key in the OS or even leave behind the orphaned registry key. This, of course, will cause the problem of missing/ invalid registry entries. Other actions include deletion of startup programs, installation of software embedded with spy-ware or changes in hardware...etc
And because of the above reasons, cleaning Windows registry has become an essential and crucial action that you need to implement regularly. Do it timely or you will have to bear a miserable ending of losing all important data due to the system breakdown.
CAN I DELETE THE REGISTRY BY MYSELF?
The answer is "No". When you attempt to remove the registry by your own, the risk that you may remove the valid registry is high because without the registry cleaner software, it is not easy to determine which registry belongs to which application. Therefore this may cause the system to crash or the software to malfunction.
