MV RegCleaner analyzes your Windows Registry in search of invalid keys that may be affecting your computer's performance. After a fast scan, it displays a list of all the problems found, usually due to broken links, inappropriately uninstalled software or usage traces that are no longer valid.
The issue here is that you must be very careful when deleting keys from the Registry, because you might end up ruin your whole system and having to reinstall. MV RegCleaner includes a "Doubts about this item" link that seems to offer more information on what you're about to delete, but it doesn’t. Fortunately it also features a Backup utility that works fine and enables you to save a copy of your Registry before making any changes to it.
