Registry Cure

Registry Cure is a simple-to-use application which locates and fixes errors which occur with your Windows registry keys, in order to boost the performance level of your computer.
The interface of the program is clean and pretty intuitive. So, you can opt for a smart scan (which is quicker), custom scan or for a complete one (which is thorough).
Registry Cure can look into ActiveX and COM issues, uninstall and font entries, shared DLLs, application paths, help file information, Windows startup items, file path references, file associations, sound and application events, invalid class keys, type libraries, program shortcuts and empty registry items.
After the scanning process is over, you can check out the total number of errors, along with a name and description of each invalid registry key. Plus, you can read statistics (errors, cleaned, ignored)
Furthermore, you can create an exclusion list, schedule tasks, backup the registry, enable Registry Cure to automatically run at system startup, create a system restore point before fixing errors, log scanning results and to exit after the job is done, and others.
The program requires a very low amount of system resources and can take a while to complete a scan and clean job. However, Registry Cure crashed a couple of times during our tests when we tried to fix errors. Plus, the unregistered version has some severe limitations and its response time is not very good. We recommend Registry Cure with reservations.
