# UI inspector

To study the interface structure of Windows desktop applications, Astro Studio has the UI Inspector panel. To start working, you should click the "Update the Tree" button ![](/files/eCJBoQu3zwaIEfGfx8cM). After clicking the button, the inspector will start to inspect all running applications and display the application structures that have a graphical interface. The left part of the panel displays the control tree.
