Why Clean the Registry?

The Registry is one of the most vital and the most vulnerable to errors part of a computer. Programs access the Registry thousands of times per second and new registry entries are created whenever new software or hardware is installed. Most programs delete their entries when they are uninstalled, but some applications leave a lot of their registry keys behind. That's how invalid entries mount up and the Registry becomes cluttered with unused and corrupted keys and references. As a result the system needs more time to access the Registry and find the entries it needs, which causes dramatic computer slow-downs.

Among other things that can lead to Registry problems are poorly written applications, incorrect program uninstalls, and bloated browser cache. All this can cause system errors, crashes, and failures. That's why it's extremely important to keep the Registry in top form by regularly cleaning all the junk and fixing all the errors that accumulate over time.
