Window Inspector is a comprehensive tool for viewing window class, properties, text, and more.
You will be provided with real-time information regarding application windows within an in-depth display by merely selecting a target window. There are default hotkeys that allow you to quickly freeze any info, save it to a file, or lock on a particular window to view its properties changing in real-time. You can consider it a handy turbo-charged alternative to your system's task manager.
Window Inspector permits you to easily browse through the hierarchies of parent/child or owner/child windows per-process, as well as viewing any of the windows associated with a target application. You will double-click upon any window on the left-side tree view to open its detailed properties, icons, and more. By having the ability to view these items, you may run down unwanted messages (pop-ups) originating from equally unwanted apps.
