• Search for specified windows, threads, processes, or messages.
• View the properties of selected windows, threads, processes, or messages.
• Select a window, thread, process, or message directly in the view.

Usage

There are two versions of Spy++. The first version, named Spy++ (spyxx.exe), is designed to display messages sent to a window that is running in a 32-bit process.

The second version, named Spy++ (64-bit) (spyxx_amd64.exe), is designed to display messages sent to a window that is running in a 64-bit process. Although the Spy++ (64-bit) file name contains amd, it runs on any x64 Windows operating system.
