AutomationElement.RootElement Property

You can use the root element as a starting point for finding other elements, using the FindAll and FindFirst methods.

When searching from the root element, be sure to specify Children in the scope of the search, not Descendants. A search through the entire subtree of the desktop could iterate through thousands of items and lead to a stack overflow.

The following example code retrieves a collection of all the immediate children of the desktop.

AutomationElementCollection desktopChildren =
    AutomationElement.RootElement.FindAll(
    TreeScope.Children, Condition.TrueCondition);
