Registry cleaners, or repair programs, are software programs that do in minutes what used to take hours and sometimes days to do before they were around. What it is these software programs do is rid a Windows operating system’s registry of bad and duplicate files. Registry cleaners also determine which files are missing
from the registry and add these files to it. Registry cleaning and repairing programs also have the ability to find files that have been damaged and then replace these files with good ones.
The reason it used to take hours or days to do this was because a human being had to enter the registry through an interface such as “regedit” and find duplicate and bad files. Then, this human would have to locate the files that were needed to replace these bad files and he had to enter these new files into the registry. Doing this to replace a small number of files such as two or three was a difficult task and could take hours.
With today’s large registries and operating systems such as Windows Vista and Windows 7, it is not unusual for a registry scan to turn up hundreds of bad files when it scans a registry that is in relatively good shape. A registry that is in not such good shape may turn up thousands of bad or corrupted registry files.
So, you can see keeping your registry in top condition is a job that could literally take forever if registry cleaners or repair programs were not available. Fortunately, these pieces of software are available and allow you to relax as they get all the bugs out of the registry and return it to its original pristine state.
Other than the fact they save time; another advantage to using a registry cleaner, at least at top rated registry cleaner, is you can rest assure it will do the job 100% accurately. On the other hand, even a very skilled technician could make a mistake when working in a Windows registry and if he or she did, it could make the computer run more poorly than it had been in the first place.
In fact, this sort of thing used to happen all the time. In the days before registry cleaners, someone would venture into the Windows registry in an attempt to repair it and end up with a computer that would no longer boot up. This is another reason to be thankful we have registry cleaners and registry repair programs available today!
