While scanning the registry, Registry Healer will open the tree-view window showing the invalid registry keys that have been found. By default, all entries that can be modified safely are checked for correction in the boxes on the left.
Entries that have read-only access or cannot be corrected automatically are not selected.
By expanding and browsing the tree, you can select or deselect any registry entry. Only selected items will be corrected.
Select the entries you wish to correct (or leave the default selection) and then click the Correct Selected Items tool button to apply the changes to the registry.
