Ultimate Registry Cleaner

The Ultimate Registry Cleaner scans for over 85,000 known problems - and thanks to its built-in "Registry Intelligence", it uses heuristics scanning in order to potentially find and fix millions of other problems on your PC. It checks for incorrectly installed applications, invalid file associations, failing COM and ActiveX components, badly-associated file extensions, incorrect help file locations, invalid links in the Start menu and most recently used (MRU) lists, badly formed shortcuts, incorrect shared DLLs, wrongly associated shared folders, dangerous shell extensions, poor sound configurations, un-optimized registry access, corrupt Windows fonts, hazardous startup programs.
