What is RegClean Pro and how it can benefit you? RegClean Pro is a simple to use utility which scans, detects and fixes invalid registry entries in Windows. It scans the odd areas of the registry to identify the obsolete entries which are left behind during regular usage of a computer. RegClean Pro also finds fragments scattered all over the registry. Fragments are nothing but registry blocks that store no data but still occupy space as it maintains reference to the next block. Removal and repair of such entries results in a compact and cleaner registry, enabling your computer to run faster, smoother and in a more stable manner.
