Registry Mechanic is a registry cleaner for Windows that allows you to safely scan, clean and repair registry problems with a few mouse clicks.

Problems with the Windows Registry are a common cause of Windows crashes and error messages. By using PC tune-up utilities such as registry cleaners regularly, your system should be more stable, your software quicker and your operating system will boot faster.

Registry Mechanic will scan your entire registry for invalid entries and provide a list of the errors found. You then can choose to clean each item or automatically repair them all after making a backup.

The brand new Registry Mechanic 6.0 contains a whole host of new features and improvements such as enhanced scanning and improved performance. The new Registry Pruning facility will produce a streamlined Registry, whilst the new Monitor device will enable you to view changes made to your Registry, since you last used Registry Mechanic. The new version also contains a revamped interface and many other smaller tweaks.
