Before we are able to detect registry editors, we have to understand how the registry works. Whenever we install an application on the computer, a certain data is written in the registry. These data are being accessed by the operating system every time it starts up or once you open a program to locate a specific file destination or to perform a task.



Once you uninstall a program, the ideal thing is to have the application's registry entry deleted. However, this does not happen all the time. The program usually leaves behind unnecessary and unwanted files that are usually corrupted. These are often referred to as orphaned registry files.

Since the system would refer to your registry to run applications once you start it up, it may have the tendency to mistakenly refer to these orphan files even if the supposed application is no longer on the computer. Because the computer spends more time to look for these applications, you will notice how it suddenly boots slower than the usual. That would be the first indication you will get to detect registry errors.

Other causes of registry errors are spywares, viruses and Trojans that come in bundle with downloaded programs. Once you install these on your computer, completely unaware of its implications, you may unknowingly key in corrupted and even infected files in your registry.

Infected registry files will cause malfunction as you run your computer. It may cause some application to fail and may even affect your whole system altogether. You will detect registry errors that are due to infected registry files once you are prompted with error messages that are looking for missing registry files or are telling you that the registry files you need to launch an application is corrupted. A worse case scenario for any type of user is being prompted with the blue screen of death. Once your computer experiences such errors, chances are the only solution left for you is to reinstall your operating system which is not easy to do especially if you have important files stored in your computer.

To solve these problems, you may need to correct and fix these corrupted registry entries that are vital to the system's performance. Orphaned registry files that are causing your computer to run sluggishly have to be completely eliminated to maintain the optimum performance of your computer. In order to do all these, you have to detect registry errors by running a registry scanner on your computer.

Registry scanners look into your registry to match up registry files with the applications that need it. If it finds potential errors, corrupted and damaged files, as well as missing files, it would prompt you accordingly. Most registry cleaners offer free scanning. Once it scans your registry, you will be asked to purchase the software to fix the problems at hand. Nonetheless, there are free softwares that do not only detect registry errors but most often than not, you really have to pay for the quality.

After fixing the registry's problem, you will notice a great difference with your system's performance. Most of the applications you were not able to launch will now work just fine. But sometimes, you may need to reinstall these applications for the treatment to apply.

Once your registry is running pretty well, you still have to keep your registry tidy by running a schedule scan at least once a week. This will prevent other registry errors from doing more damage on your computer.
