WinSpy++ is a programmer's utility for inspecting and modifying window properties of any Windows program.

WinSpy++ requires Visual Studio 2015 (with "MFC" and "Windows XP support for C++" features installed), and supports Win32 and Win64 builds. Use the IDE to build WinSpy++, or the build/build.bat command-line script (requires Ruby) to build and package a zip file for distribution.

The fork introduces the following improvements to the original WinSpy++ 1.7:

• Visual Studio 2015.
• Complete Win64 support.
• Window properties editor.
• Autoupdate button, which refreshes the window properties periodically.
• More extended styles.
• lots of bug fixes and small improvements.
• Broadcaster feature to broadcast send/post messages.
