How to Clean a Registry Safely

Level of difficulty: Intermediate

The Windows Registry is one of the most complex components of the file system of every computer system running under the Microsoft platform. It affects not only the behavior of the Operating System and installed programs but also on how the pieces of data are stored on the hard drive. Every time certain software is installed or uninstalled, a corresponding registry key value entry is created or deleted. This affects the integrity of the Windows Registry service. The frequency of this operation however may lead to orphaned file traces in the registry or broken links that may cause the file system to behave erratically; thereby, leading to a drastic slowdown or possible crashing of the computer. In the long run, the Windows Registry may become too populated with obsolete programs or entries that are no longer accessed by the user, all of which will negatively impact the computer system’s overall performance.
