It is recommended to use a registry cleaner when the system performance is very slow and it starts to hang when doing some operations. A Registry cleaner scans the entries of the windows registry and scrapes away all the information that are no longer needed or those broken registries that could be hampering the PC’s performance. One solution to these issues could be using a registry cleaner software. These are invalid or broken registry and they may cause errors and may lead to slowing down of the system. The registry keeps a record of everything, as a result it even has the information on a program that was uninstalled earlier. When you install a lot of programs, the registry gets loaded up with information from all those programs. Whenever a program is installed, a new entry containing information such as the location of the program, its version and how to start the program are all added to the Windows Registry. The registry or windows Registry contains information, settings, options and other values for programs and hardware installed on all versions of Microsoft Windows operating systems.
