Registry Clean Pro is a utility that safely removes invalid entries from the Windows registry, thus optimizing the performance of your computer. By default, Registry Clean Pro scans the registry for all types of invalid entries. However, you can use the Custom Scan option to search the registry for particular types of errors. After the scan is complete, Registry Clean Pro can show you a full list of errors, allowing you to choose the invalid entries to remove. You can even schedule Registry Clean Pro to scan the registry every day, once a week or once a month. Registry Clean Pro can check the registry in background mode and alert you when it finds any errors.
