What are Registry Cleaners?

It is obvious from the name what registry cleaners do – they clean your registry of course. But what is your registry and why do you  need to clean it? Your computer’s registry is the place that all the information for your operating system to function, exists. In addition, your registry contains information about software and hardware programs on your computer. With all the programs you install and uninstall as well as all the malware and viruses that get on to your computer, your registry gets cluttered with all kinds of junk files that slow your computer down and can often cause errors and crashes. A registry cleaner will clean out all of the unnecessary junk and get your computer optimized like it was new.  The best registry cleaners will even scan for malware and viruses and will give you the option to remove programs from your autostart that are slowing you down.
