If you want to keep your computer functioning smoothly, efficiently, and speedily, one thing you need to do is keep your registry free of errors. Your brand-new PC is not unlike a newly installed kitchen counter: clear of mess and rubbish. Several months pass by, and all of a sudden, your counter tops are just gone. Your computer is just like this: at first, it runs just fine. It runs properly, loads programs without much hassle, and can open documents without a problem.
