Automate Windows desktop applications from Python using pywinauto

Steps

1. Install pywinauto with `pip install pywinauto`, then connect to a running application by title: `from pywinauto.application import Application; app = Application(backend='uia').connect(title_re='.*Notepad.*')` — use `backend='uia'` for modern apps and `backend='win32'` for legacy apps.
2. Launch a new application: `app = Application(backend='uia').start('notepad.exe')` — pywinauto waits for the main window to appear before returning.
3. Retrieve a window or dialog: `dlg = app.window(title_re='.*Notepad.*')` then access controls: `dlg.Edit.type_keys('Hello, world!', with_spaces=True)` — control wrappers are resolved lazily by control type or name.
4. Click buttons and menu items: `dlg.button('OK').click()` or navigate menus with `dlg.menu_select('File->Save As')` which handles the full menu chain.
5. Inspect the application's control tree at runtime with `dlg.print_control_identifiers()` — this prints all reachable controls with their identifiers, helping you write correct selector strings.
