Free Error Cleaner is a program designed to detect and repair errors in Windows systems. This freeware uses high-performance error identification algorithms to scan the Windows registry for missing or invalid references. Once it has identified a problem, it can repair it automatically after every scan. In addition to being free to download and use, it also creates automatic backups to ensure that your system is stable. It will even help you fix your system's registry if you experience any trouble in the future.
This program can also undo changes that it made to the Windows registry. After running the scan, the program will notify you of the problems and repair them. You can also configure the program to create backups every time it finds something wrong. You will not have to worry about paying a dime to use it, since it's free. If you run into any errors, you can even select "restore" to undo the changes, if you want to revert to the original state.
The Free Error Cleaner can scan specific areas of the registry, which can make it very useful for advanced users. It can also remove unused programs and toolbars from your system, which helps you optimize it and speed it up. Additionally, it also lets you disable some of its search parameters so that you can only use the best ones. Aside from fixing errors, it also backs up your registry before completing a scan.
