Registry cleaners are special programs that automate the process of scanning your Windows registry for errors, and then fixing them.
Doing this manually could take several hours, and you might never find all the errors.
Also, if you don't know what you're doing, tinkering with it can cause severe problems and even make your computer unusable.
These cleaners enable the average user to conduct regular registry cleanups in order to keep their computer running smoothly.
What is the Windows Registry? The Windows registry is like a central filing cabinet where Windows stores important data related to user settings, program preferences, and hardware configurations.
Just like a normal filing cabinet, over time it can become messy and disorganized.
Actions like the installation and un-installation of hardware and drivers can result in orphaned files, broken or missing folders, and general messiness.
When the registry becomes too messy and disorganized, Windows has a hard time finding critical files.
This is why your computer crashes, freezes, slows down, and displays error messages.
Running cleaning software enables you to clean up all the junk.
A recent test scan with the program RegCure revealed over 800 obsolete or broken reg entries on a sample computer.
Signs you need a Registry Cleaner One of the first signs of a damaged or corrupt registry is a slow bootup.
This is the time when Windows is setting up all the user profile data and is heavily scanning this data.
Too much "stuff," like broken files, greatly slows down this process as Windows has to spend a lot of time searching through the old, obsolete, and even corrupted entries.
Another sign is frequent error messages.
These errors could come from programs, hardware, or even Windows itself.
If Windows can't find the correct files then the programs and hardware will not run correctly.
Registry problems can also lead to computer crashes and freezes.
The infamous "blue screen of death" occurs when a massive error occurs that stops all programs in their tracks.
This is never a fun problem, and can cause you to lose hours of work.
The Best Registry Cleaners A good repair program will allow you to make backups and be able to restore the computer just in case a file you chose to remove is actually important.
Good registry cleaners will also scan your computer fairly quickly, and find the same (or roughly) number of errors on two scans.
