Let us first understand the working of the computer registry repair tool. First of all it has to verify whether all the entries in the registry are valid. If it finds invalid registry entries, it has to remove them first. Then it has to check for the entries which are corrupted or changed by malicious software or viruses and fix it. At the later stage to increase the speed of accessing the registry, the computer registry repair tool has to de-fragment the computers registry.
There are certain features you need to look for in a good computer registry tool. It must be capable of fixing errors that cause registry problems like dll errors, appearance of blue screen and other error messages, crash and freeze of the system continuously etc. When you are continuously browsing on the internet there are several temporary files that are created to store details of your sessions and temporary download files too. These take up too much space on your system and if not cleared from your system, it will make it completely slow.
