Advanced Registry Optimizer is the easiest and most comprehensive way to keep your PC running cleaner, faster, and error-free. With the Backup and Restore tools, you can guard against system failure. Thus, you can always revert to the last good configuration and minimize the chances of viruses and bad installations. The program even lets you create a simple emergency boot disk for starting your system. Registry Cleaner and Optimizer cleans the Windows Registry of invalid information; it goes far beyond the simple RegClean and cleans ActiveX-COM-OLE sections, user software settings, system software settings, the shared DLL section, the fonts section, file associations, run sections, sound, the uninstall section, virtual device drivers and services, and application paths for invalid entries. Finally, Registry Defrag optimizes the Registry by removing fragmentation, deleting unused entries, and compacting the Registry.
