Windows operating system consists of a database naming Windows registry, which lists all the configuration settings. Windows registry can also save some of the unnecessary files and other items. So, it will become necessary to remove such files from the Windows registry. For this task, you can use a software utility naming registry cleaner.
Concept of Registry Cleaner
Registry cleaner is a useful utility, which removes configuration data from Windows registry that is no longer in use. Many registry cleaners are available in the market, like PC Registry Cleaner, Eusing Registry Cleaner, Registry Mechanic, CleanMyPC Registry Cleaner and many others. You have to research about registry cleaner before downloading it from the Internet.
In case, you want to edit Windows registry, then you have to access it by running regedit.exe or regedt32.exe in the Windows directory. But you should take back up of the registry before doing any changes into it. It is necessary that you should have the proper knowledge about the Windows registry otherwise you can cause irreversible damage to it.
Registry Editor enables you to perform various functions, such as:
• Creating, manipulating, renaming and deleting registry keys, subkeys, values and value data
• Bookmarking user-selected registry keys as Favorites
• Importing and exporting .REG files, exporting data in the binary hive format
• Loading, manipulating and unloading registry hive format files
• Setting permissions based on ACLs
• Finding particular strings in key names, value names and value data
Along with advantages, registry cleaners also have some disadvantages. Registry cleaners, which are designed poorly, can cause loss of functionality or system instability. A number of Trojan applications can take benefits of registry cleaners to install malware. This utility is unable to repair some issues like undeletable registry keys which are caused due to embedded null characters in their names.
It is of no use to clean registry entries, which are linked with a virtualized application from a registry cleaner. The reason behind this is these entries are written to a particular virtual registry as compared to real. Registry cleaners are not able to remove entries linked with rootkit. So, you have to take care while installation of a PC registry cleaner.
