Registry cleaner key clean up is the process that fixes most of the problems in the Windows registry. Registry keys are the ones most often left behind when a program is installed. Those stray keys are bits of information that the computer no longer needs, and they become clutter. Registry cleaner key clean up programs attempt to clear those out and make things work better.

Some registry keys aren’t actually generated when the program installs, so the program installer doesn’t even know they’re there. These keys are generated by the program itself. When the time comes to uninstall the program, since the installer didn’t put them there, the uninstaller doesn’t know to remove them. This causes the need for registry cleaner key removal.

Registry cleaner programs sweep through the registry and remove leftover information like keys and other things that are left behind when programs are uninstalled. Every computer that uses Windows has this registry. It’s a vital part of the computer, as the computer cannot run without it.

Every program deposits information in the registry when it’s installed, and later as it runs. The computer refers back to this information constantly as it’s running those programs. A registry key is really just like a folder on your computer. In this case, different keys contain different information relating the operation of a specific program. A program can have several keys.

These folders can be quite large, holding a lot of data, or small. Both types are left behind. This is what can cause the annoying problem of a slow running computer. A registry cleaner key clean up can remove those and make it easier for the system to find the information it needs.

Using a registry repair program, whether you’re running an old version of Windows or a newer one like Windows XP or Windows Vista, can drastically improve the time it takes for a computer to boot up. Several seconds, and sometimes minutes in the case of a slow booting computer, can be shaved off the time.

Hanging screens, lags and freezing can be eliminated after registry cleaner key removal, too. And sometimes the problem isn’t that a key was left behind, but that one was removed when it shouldn’t have been during a program uninstallation.

Sometimes when a program is removed, a file that it was using but is also used by other programs is removed. This can cause the other program to work incorrectly or not at all. If that program is a system file, freezing and crashing can occur.

When you run a registry cleaner, removing keys isn’t the only purpose it serves. It can find problems resulting from missing keys, too. And many programs can perform further useful functions like compacting the registry. This helps the large registry take up less room on your system.

There are other ways to remove keys from the registry, like removing them manually after a program uninstallation. But a registry cleaner key removal program is by far the easiest way to fix your system’s registry problems.
