Here is an alternative Managed API to FindWindow, The article also describes a way to CloseWindow of another process like notepad, not sure if there is such thing in Win32 API, but at least you can do it in .NET! Here is the article:

        return SafeNativeMethods.CloseWindowStation(handle);

See [Enums.ACCESS_MASK] and [CloseWindowStation].
