While you don't need to be a rocket scientist to scan and repair your PC's registry (it's really easy with the right software) it does help you know a bit about the registry. This short article will give you an overview of this essential part of the Windows operating system.

See all those settings on your computer? Well they don't just float around aimlessly. They've got a home. That home's the Windows Registry - a huge bank of information about everything that's on your computer.

Change your Windows Wallpaper and it's stored in the Registry. Install a new font on your PC - it's stored in the registry. In fact, it's pretty hard to do anything on your computer without the registry getting involved.

Without heading too far into Cliche City, the Registry is a bit like the nerve center of your PC. Any time it needs to know something, it goes and asks the registry. And Windows just loves the little guy. It can ask it for information dozens of times in a single second. So the registry gets lots of use.

Another essential part of the registry is what are called Keys. If the registry is a hive holding thousands of bits of information in it, then the Keys are the worker bees. Keys are the little holders that keep the individual information within them. Keys can be created by your computer, deleted or just looked at when it needs to know something.

Douglas Adams once wrote: "The Universe is big. I mean, really big..." Well, the registry's big too - REALLY BIG. And that's kind of it's problem. Like a janitor who's getting a bit long in the tooth, and having trouble with his rounds, Windows just can't seem to keep it's registry clean.

Problems in the registry begin when you uninstall a program, move a folder or do any one of a number of pretty ordinary tasks that we do every day. You see the Registry is a bit on the lazy side. It doesn't do a very good job at optimizing and cleaning itself. And bits get left behind. Junk. Clutter. Pretty soon it all mounts up.

While a bloated, chubby registry isn't the worst thing that can happen in life, it's still a serious problem that's worth getting under control. A broken registry means more of those annoying computer errors: crashes, computer slowdown, error messages and loads of other really irritating problems.

OK, we've learned what the registry is and what happens when it misbehaves. But how do you get it to tow the line again? What's the easiest way to get it back in shape? Like a spoilt teenager, it needs some discipline. And the best form of that is to scan and repair the registry.

If you think scanning the registry is difficult, it's not. All you need to do is download a bit of software, click on the 'Scan' button. Wait a bit. Wait a bit more. And then click on the 'Clean' button. It's safe. It's fast. And it really does work. Anyone can - and should - be doing it.

Whether you use your PC for work, gaming, or both - you'll find you get a juicy performance boost when you scan and repair your registry. Some tools even include extra gadgets to get your PC running on top form again - like memory tweakers, startup optimizers and registry compactors. (Try saying that after a few beers).
