How to handle window move?

[generic]

I'm using GetWindowPlacement and SetWindowPlacement, too.
The difference is, i'm storing the record "TWindowPlacement" to registry as binary stream.
This saves some keys.

There is a small pitfall. If the monitor configuration changes by removing a second monitor, then the windows will still restore on the old position (on that not available monitor).
The cause that the user isn't able to see or move the window.
