A registry repair cleaner, often just called either registry repair or registry cleaner, is a program that fixes the errors in your computer’s registry. The registry is like the brains of your computer. When you install a program on a computer running Windows, the important information about its configuration is stored in the registry for the computer to refer to again and again. When things go wrong there, a registry repair cleaner fixes them.
If your registry disappeared completely, your computer couldn’t work. So when an error occurs in your registry, strange things can start happening with your computer. A registry repair cleaner is often used because the computer is running very slowly.
Sometimes, speed isn’t the problem as much as programs that freeze, won’t run properly, or lose data. Errors in the registry often will affect only certain programs because somehow that program’s registry entries became corrupted.
Sometimes the problem is more widespread, though. Errors in the Windows registry entries of programs that are vital system programs can cause serious problems, like the entire system freezing and crashing. Errors in the registry can gradually become so bad that the computer won’t even start up properly.
A registry repair cleaner program can help prevent the more serious problems stemming from registry errors. When the first problems show up, using a program designed to fix the Windows registry can find the errors and repair them so the computer runs correctly.
But if a problem arises with just one program, or when you try to do just one certain thing, and isn’t fixed, it can grow into a bigger problem. Because there is one error, that means the likelihood of more errors is even higher.
Errors usually occur when a program is being uninstalled. All of the files are often not removed properly, and end up cluttering the registry. When your computer runs, it constantly pulls information from the registry. Eventually, enough stray files are left behind that the clutter makes it difficult for the computer to pull out the information it needs.
That’s the chief cause of a computer slowing down because of registry problems. And there’s really no way to prevent those files from being left behind during an install. So running a registry repair cleaner at regular intervals should really be considered part of regular computer maintenance.
Even if the computer doesn’t slow down, often those cluttered registries will start to produce runtime errors, and missing or corrupted DLL errors. These can also occur if the uninstallation of a program removed a file that’s vital for other programs to work. Usually the program gives you the option of keeping those files, but sometimes they’re removed, causing problems.
A registry repair program can detect if you’re missing vital files, as well as removing those files that are corrupt, old versions of new ones, or not needed at all. Most registry repair cleaner software will even scan first for errors and tell you how many there are before it starts repairing them.
