You can choose to undo your changes at any time while you are configuring your computer. You can undo all changes or you can undo just the changes made in a branch of the configuration tree for any unsaved changes.
Highlight the branch of the tree for which you want to undo all changes. For example, if you want to undo all changes you made in the Device Settings branch, highlight Device Settings.
From the Main Menu, choose Edit > Undo Item Changes. A dialog box appears asking if you want to undo changes.
Click Yes.
