What Does a Registry Cleaner Do?

Registry cleaners are one of the most desirable computer maintenance tools that both computer users and technicians depend on to perform preventive PC maintenance. This need is triggered by the fact that the registry has a great affinity to attract a lot of junk information that has a tendency to cause severe damage to it.

These tools usually comprise a user-friendly graphical user interface that makes them easy-to-use even to non-technical users, and enables them to maintain a healthy error-free registry.

A good registry cleaner tool uses advanced and complex algorithms to scan deep within your registry and identify all unwanted, incorrect, and malicious information contained in it.

An advanced registry cleaner tool categorizes the detected errors in such away that it is easy for you to go through them, identify, select, and delete all erroneous entries. If you are not sure about which entries to keep and which to delete, you can use the automatic repair option to allow your registry tool to automatically perform all the fixes.

When you fix the registry using an advanced registry cleaner tool, you indirectly fix many other computer errors, such as stop errors, driver errors, ActiveX errors, and DLL errors. The advanced algorithms used by advanced registry cleaners enable them to search for keys that are entered as embedded or non-removable keys. These keys are primarily used by software applications to store licensing information. However, many spyware programs exploit the fact that these keys are practically non-removable, and use them to enter data that enables them to become difficult to remove from the system.

It is quite beneficial to run registry scan after you have uninstalled an application from your PC. This is important because many times, when you uninstall an application—especially a large application—it leaves behind too many orphan keys that clutter the registry. Following up the uninstallation process with a registry scan helps you detect and remove these unwanted keys.

You can use the registry cleaner tool to defrag the registry. Defragging helps you in consolidating the registry files by reindexing and compressing them by getting rid of all undesired vacant registry keys left behind by removed keys. If you really want to reduce the size of the registry, you must follow up all registry scan and repair activity with the registry defragmentation process to remove the vacant registry keys left behind when unwanted and invalid keys are removed during the repair process.

Registry backup options are one of the most important features of registry tools. A good registry tool always makes automatic backup of the entire registry before performing any repair process. This way if your registry cleanup activity fails, you can easily undo the changes by restoring the registry from the backup. You can also use the tool to create full and selective registry backups according to your needs. One of the most sorted out features in a registry tool is the undo feature. This option enables you to undo your registry edit actions with just a simple mouse click.

Many registry cleaner tools also enable you to perform a few other system maintenance activities such as managing startup programs, Internet Explorer files, and other orphan and unnecessary system files.
