Does anyone know how to detect if a Win32(c++) window has stopped moving?

WM_MOVE detects when the window is moving, but how does one detect when it has stopped moving?

You don't really know it's moving, all you know is that is has moved. The difference is subtle. - Mark Ransom
So, WM_MOVE triggers when the window is not moving? Edit: You are right. - James Diaz
Yes, Sent after a window has been moved. WM_MOVE message (Windows). - Zilog

The windows message you wish to handle is WM_EXITSIZEMOVE.

Depending on what you wish to accomplish, there's also the possibility that you might be better served by reacting to WM_NCLBUTTONUP, which is sent when the mouse button is released in the non-client areas of a window, such as the title bar of any window with a caption, border chrome, etc.
