What are Registry Cleaners?

Being a computer is tough. You process things all day and need to do it in record time to keep the user happy. It is frightening to imagine how a computer manages all these things. The answer is pretty simple though. The Windows operating systems have a fantastic system in place that makes information readily available for the processor. This information is stored and organized in a database we call a registry. The Windows registry manages everything a computer needs to know to do its job. The problem is that this registry can get cluttered over time and especially if the user has installed a lot of programs. This makes the registry cleaners a wonderful thing to have on hand.

Registry problems arise if there are tremendous amounts of unnecessary entries in the registry. This usually occurs when a person is not well educated about the installation and uninstallation process. It may have occurred to them that if they deleted the folder in the Program Files, the application would no longer run. That is right. It will definitely not run. However, the computer still thinks the program is installed because the registry was not made aware of the deletion. That is why there is an uninstall file always accompanying the programs we use. It has a built in batch file that handles the cleaning of the registry entries. Registry cleaners were created to serve this purpose. Developers are well aware that this is a growing issue and so they developed these reg cleaners.

Registry cleaners also have other tasks aside from detecting obsolete software. They are also able to detect missing shared DLLs. This means that it can detect if an important DLL has disappeared from the computer. This is a big help since DLLs are important in the functionality of programs. When these are detected, it is up to you to find a way to get these DLLs again. The registry cleaner simply tells you what you are missing.

The registry also manages and stores a list of the file extensions we use. Some of these are .exe, .ico, .jpg, .doc and many more. Some of the programs we use have their own specific file extensions. For example, Photoshop is known to have the .psd file extension. When we uninstall Photoshop, the registry sometimes mislooks the .psd extension. If it is not removed along with the program, a registry cleaner will be able to detect it and will list it as an unused file extension.
