Here are just some of the great features of Registry First Aid:
Easy to use step by step Wizard type interface.
Registry First Aid scans registry for orphan file/folder references.
Quickly finds these files or folders on your drives (if they're moved from initial locations).
Corrects registry entries to the located objects.
If your registry still retains links to files of deleted applications, Registry First Aid will find these invalid entries and help you to easily remove them.
With this powerful tool, your Windows registry will be always clean and correct!
