Registry Cleaner - The registry is a key component of the Windows operating system. Without it, Windows would not be able to run. The registry is stored on your computer in several files and depending upon your version of Windows, there will be different files and different locations for these files.

The Windows registry is a database repository for information about a computer's configuration. The registry keep growing when you use Windows. As it does so, it attracts obsolete and unnecessary information, and gradually becomes cluttered and fragmented. With the growing of the registry, it can degrade the performance of the whole system and cause many weird software problems. The more software and hardware you install and uninstall, the more full your Registry gets. A great deal of software doesn't clean up after itself, and leaves behind old and obsolete Registry entries, or upon install creates invalid ones. There will be pointers to missing DLLs, listings of no-longer-valid file extensions, invalid paths, invalid ActiveX Controls, and much more. The more your Registry fills with this junk, the slower your PC gets and the more often you'll have system crashes.
