The screen is divided into 3 parts. The first one at the left side is the main area where you can activate what kind of Registry entries the program should check for. You can set or remove a checkmark or use the buttons 'Select all' or 'Select none' below the list.

Whenever you click on a registry entry type at the left side you will get some short information about that in the box at the right top because not every user normally knows what entries like 'RunMRU' mean.

The right bottom of the screen allows you to undo changes made with this program. Deleted files normally are moved to the Recycle Bin but this is not possible for Registry entries. Here you get a list of backup files including date and time of Registry changing. By double-clicking one of these entries a *.reg file will be executed that reverses the changes. Just confirm the security hint that is shown on most systems and your Registry will be the same as before cleaning.

Like it is for all search and delete configuration screens of this program you can set or remove the check mark at the left bottom of the screen if this section should be included when you click on 'Analyze' or 'Run'.
