When errors occur, it is important to be able to repair the Windows registry so as to fix them and to prevent future errors from occurring. You will find that random Windows freezes, error messages and performance slowdowns are good indications that it’s time to do something about the registry.
When there are problems in the registry, these will eventually cascade upwards to affect Windows as a whole. If neglected, these errors can compound. Registry errors develop in the course of using Windows and applications. Data is stored and retrieved from the registry constantly and due to various reasons, invalid data is kept in the registry but are not updated or deleted. As time goes by, the invalid data grows and the registry becomes cluttered with wrong information and inconsistency. As a result, errors occur.
In the past, the only way to fix registry problems is to format the computer and install Windows again from scratch, unless one is a technical guru. An expert can directly edit the registry and fix problems, but the registry can grow to a huge size, making this process tedious and time-consuming. In addition, any mistakes when editing the registry can bring down the system.
Nowadays, we use registry cleaners to do the job. A registry cleaner is a software that automates the task of scanning the registry no matter what size it is. The software scans for errors and fixes them. There are many such software available but not all are good. Good ones perform a thorough job of finding and fixing problems, as well as optimize the registry to let Windows run faster and reliably.
