Registry Healer will check the entire registry to make sure that there are no broken entries. This will free up a lot of space in the file, which can speed up Windows.

Registry Healer is particularly useful if you tend to install and uninstall a lot of programs. By putting it to work, it will help you clear out the junk that commonly fills up the Registry. Unlike similar utilities, this program doesn't simply (and dangerously) remove items from your Registry. It will attempt to correct invalid entries by finding matching folders and files that may have been moved. A separate component lets you select directories to scan. You will be able to instantly "heal" invalid entries, and safely delete some others.

Registry Healer provides a few other features for advanced users. The program provides one-click access to a registry key with the Windows RegEdit tool. Furthermore, you can highlight a reference and jump directly to the directory that it's pointing to. Finally, you can create "undo" files in the RegEdit format and full system backups. This lets you conveniently restore a Windows Registry to a previous state using native Windows® tools (even without having RegHealer installed in the system).
