Identify a window by its handle
It's common in flow development to create flows that use several windows with the same title and class.
Power Automate enables users to distinguish identical windows using handles. Handles are numbers that uniquely identify each window.
To retrieve the handle of a window, launch the application with the Run application action and set the After application launch drop-down menu to Wait for application to load. The handle is stored by default in a variable named WindowHandle.
Alternatively, you can use the Get details of a UI element in window action to retrieve the handle from an already open window.

You can use handles to manipulate windows through the following Windows actions of the UI automation group:
