A: The Windows registry is a central categorized record in Windows operating system used for storing information required to configure the system for users, applications, and hardware devices. The registry contains information that is continuously referenced during operation, like profiles of users, applications installed on the computer, and types of documents each application can create, sheet settings for folders and application icons, types of hardware on the system; and which ports are being used. Windows registry is an essential part of Windows. If it is damaged, your whole system may be corrupted and result in Windows crashes.

A: Over time with normal use, your computer's Registry will become bloated and filled with obsolete or unnecessary entries. This is especially true as software, drivers, and hardware components are added and removed from your computer. With so many additions, deletions and other modifications, your Windows Registry can become filled with errors such as empty destinations, orphaned references, or it can even become corrupted. The need for you to clean obsolete Registry settings or repair your Registry errors becomes essential to ensure optimum performance of your PC.

A: The registry becomes erroneous when it contains invalid information. Some causes are the following:
Not using certain applications for a long time;
Downloading and installing new versions of applications without removing previous installations;
Uninstalling software without using the "Add or Remove Programs" feature in the Control Panel;
Moving a file or object in the registry manually.
