When searching for top-level windows on the desktop, be sure to specify Children in scope, not Descendants. A search through the entire subtree of the desktop could iterate through thousands of items and lead to a stack overflow.

If your client application might try to find elements in its own user interface, you must make all UI Automation calls on a separate thread.

The following example shows how to use FindAll to locate all enabled buttons in a window.
