Whenever RegVac removes an entry from the registry, it puts it in a special Undo REG file.  The entries in this Undo REG file can be viewed on the Undo page.  The Undo section will display different Undo REG files and restore all entries in that file.  If an Undo REG file is double clicked outside of RegVac all of the entries in that file will be restored to the registry.

Above the Undo List is a checkbox called Check / Uncheck All.  Checking or unchecking this checkbox will check or uncheck all items in the Undo List.

There are four buttons below the check listbox.

The Print List button allows you to Print a list of the entries.

The Show Key button allows you to view the selected key in RegEdit.  To view, select an entry and then click on the Show Key button.

The Restore All button restores all of the items in the undo list.

The Restore Checked button restores only the items which are checked.

It is recommended to keep an Undo REG file for a week and then delete it if you have had no problems.  The Undo REG files can be deleted by selecting it in the dropdown box and then clicking on the Delete Current Undo File.

The checkbox at the bottom of the page allows for the automatic deletion of Undo REG files that are older than a week.  If checked, Undo REG files which are older than a week will be deleted.
