You can inspect a Windows UI tree by targeting a running application via HWND, PID, process name, or window title to generate a structured JSON or XML visual tree with stable element IDs for automated reasoning.
Yes, UI framework detection supports WinUI 3 and WPF applications, alongside Win32, ComCtl, Windows XAML, Avalonia, and Chromium, by analyzing the visual tree to identify the underlying UI framework.
Yes, you can capture annotated screenshots that overlay stable element IDs like e0 and e1 directly onto running Windows applications, providing a visual reference to map UI tree elements for interaction planning.
The best way to verify UI elements across Windows frameworks is to generate a unified element tree as JSON or XML, which normalizes element discovery and provides stable IDs regardless of the underlying UI framework.
Yes, you need both lvt.exe and lvt_tap.dll present in your environment to successfully analyze running Windows applications and extract the structured visual tree with optional annotated screenshots.
