Wise Registry Cleaner is probably the most comfortable registry cleaner that I installed on my system until now. The free software has a size of roughly one megabyte and the installation takes only a couple of seconds. The application reminds you to create a backup of your registry before you proceed which can be done right from the reminder window.
After this has been done a scan can be started by clicking on the scan button in the toolbar. The main window will be populated with the results displaying information about the keys, values, data and categories. The registry cleaner rates every entry with “safe to fix” or “Not fully safe to fix” and checks only the ones that are safe to fix.
