In fact, you can learn all you want about the registry, but completely cleaning it isn’t something you can do on your own. You can do obvious, smaller things. If you know you’ve uninstalled certain programs, you can search in the registry for anything associated with those programs. If you find information left behind from those programs, you can delete those.

But when you learn how to clean registry, you learn there’s more to it than just deleting those most obvious entries. There are also bits of information that get added every time you use your computer. a third of that information that’s left in the registry is useless. Finding all of that and removing it is something you couldn’t do (and definitely wouldn’t want to do) manually.

That’s because a day of using your computer can cause hundreds of bits of information to be added to the registry. Experts estimate that in one day of medium to heavy use, Windows can actually write to the registry up to a thousand times. In that case, about 400 different bits of information that were added need to be removed. You’ll want software for that.

You can read “how to clean registry” books and websites and get good basic information about the registry and how it operates, though. If you’re going to do anything to it, including cleaning it with software, it’s a great idea to at least understand it.

Reading “how to clean registry” information, even if you never intend to make a single manual change, can also help drive home the point that you need to do a back up before tinkering with the registry in any way, including using software.

Even the best software could inadvertently remove something that needs to be there. If that happens, your computer can show severe problems and may not want to run at all. As long as you have a backup, you can restore the registry, and the system, to the way it was. This can save headaches and frustration, just in case something goes wrong.

Fortunately, good registry cleaner software will automatically backup the registry before it starts. And most of it will rarely make a change that causes problems. On the contrary, after registry cleaning a computer typically runs much faster and much better with fewer crashes and quicker boot ups.

It’s best, especially if you’re not used to downloading software, that you choose a popular commercial registry cleaner or a very well-recommended free program. Learning how to clean registry is difficult, but choosing software can be made easier by the reviews and comments left by other users where you download and purchase the software.

When you download any free software, be wary of the sites you download from. Some websites take free software and add things to it like viruses, spyware or adware and then upload it. These third-party sites usually just have lists of software for download with no real information about each program.

If you’re at all in doubt about a site, search for the free Windows XP registry cleaner or other software you want somewhere else.

This is a try before you buy free download. You get to download the program and check it out before paying for it. The fine print will say that it’s a free trial or that the download is free, but not the application. This is sometimes called demoware or shareware.

True free software is called freeware and can be downloaded completely. When you download it, the entire program works with no restrictions, and there’s no obligation for you to pay anything.

One drawback to some freeware is that often it contains things you don’t want, like adware or spyware. Adware is built into the program. While you use the program, some part of it displays ads that you can click on. This is an active ad connection, so that when you click on the ad you go to the advertiser’s website.

Spyware is often included in free Windows XP registry cleaner software, as well. Spyware allows a third party to essentially follow you around the Internet, tracking the sites you visit and your purchasing habits. Spyware tends to slow a computer down.

Finally, to determine which free Windows XP registry cleaner software you want to use, read all the reviews you can find about the programs that interest you, and pay close attention to those reviews that report problems and errors, as well as the ones full of praise.
