The pertinent question here will be to ask when is it necessary to use a registry cleaner and why? Well, once you know what a registry is and how it works you will need to know how to clean it up when it gets full of junk. Here is where you will be educated on the use of a registry cleaner utility and where you can get one. Instructions of how to use registry cleaner will follow. So down to the first part of explaining what the system registry is.
What Is A System Registry?
The system registry is undoubtedly one of the most important parts of the operating system. It is the backbone of the system. The registry stores all the information that the operating system needs to run the PC. This information includes data pertaining to all the programs, hardware and user permissions on the system. When a user logs onto a computer by entering the username and password the system immediately refers to the registry to see what the user is allowed to do on the PC.
According the OS will proceed. If a program or application is run the OS will refer to the registry to locate the DLL files that will run the program. The registry constantly updates its database with information as the comp is used. This bloats the registry. So, a problem with the registry will reflect in the general well being of the system. This is why the registry has to be kept clean and healthy by running a registry cleaner utility when the system begins to show signs of slowing down and being sluggish.
Why Does The Registry Slow The System Down?
As mentioned, the registry updates itself with information. This makes the registry grow in size. As the registry is a hierarchical database the system refers to it serially. This means that the system begins looking for information from the beginning of the registry and goes through each entry individually. This is the case every time the operating system refers to the registry, which may be many times a second. As the registry automatically updates itself there many links and entries that are useless because the registry never deletes an entry. So when the registry is scanned the OS has to go through the useless entries as well. There are many tens of thousands of entries in the registry that lead to nowhere. These entries delay the search every time. A good registry cleaner such as PC registry cleaner or Windows XP registry Cleaner will detect these links and remove them. Then the Registry cleaner will fill the empty spaces by compacting the registry. This further enhances the performance of the PC.
