The registry is probably the cause that make your computer to run slow. The best way to fix the registry is to use a verified registry repair software. Before you to start looking into this type of programs, let us first understand what is the computer's registry.

It is a database that the operating system uses to store all the files. Every single time you type a command in your computer, the operating system accesses the registry for the necessary files to complete that command. This happens not only when you add new hardware or software to your PC, but also when you visit a web page, so now you know how many files end up in there! Actually, the majority are erased right away, but some remain, and as time goes by, the registry just is not able to hold all of them.
