Microsoft saw the need to combine all that information into one space and one program which is the registry. It stores everything from program settings and data to operating information. Anytime you utilized any type of program you will have added values show up in your registry.
Cleaning Up The Registry – What makes the registry need cleaning? After some time of using your computer, and adding and deleting programs, things begin to clutter your registry. When you delete a program all the files are not necessarily gone from your registry. Now they are cluttering it up.
Your computer is a ‘reader’. The smoothest and fastest read of the alphabet is if the letters are in order like a,b,c,d,e,f,…..and so on, but when these letters are out of place and there are random letters just hanging out like a,f,f,e,i,m,i,w,….. it takes longer for the ‘reader’ to sort it out and read it.
A registry cleaner will scan the registry and take out the redundant files and put everything back into a good working order. Then your computer will not have to work so hard to read your files and will in turn speed up.
Most cleaners come with good backup programs so if anything goes wrong your files can be restored to the state they were in before you began the cleaning. You can find plenty of free registry cleaners online, but you want to make sure you have the best one for your computer. Go into forums and ask questions and visit review sites to see about good support and effective cleaners.
