Registry Life is a free application (or website) for Windows that helps users maintain and optimize the Windows registry. It can be used to clean and repair the Windows registry to improve system performance and stability. It scans the registry for invalid and obsolete entries and offers options to repair them. It also offers a backup and restore feature to let users undo any changes they don’t like. In addition, it can defragment the registry to improve its performance and compact its size. Registry Life also features a registry monitor to keep track of changes made to the registry and a startup manager to control which programs run at startup.
