Confirming success on Vista x86!

Additionally, there is no need to keep the window lying around. Calling  
DestroyWindow immediately doesn't seem to be causing any problems.

[DllImport ("user32.dll", EntryPoint="DestroyWindow",  
CharSet=CharSet.Unicode, CallingConvention=CallingConvention.StdCall)]
internal extern static bool Win32DestroyWindow(IntPtr window);

[...]

// No idea why we need to create that window, but it enables visual styles  
on the Windows platform
IntPtr window = Win32CreateWindow (WS_EX_TOOLWINDOW, "static", "Foster  
Parent Window", WS_OVERLAPPEDWINDOW, 0, 0, 0, 0, IntPtr.Zero, IntPtr.Zero,  
IntPtr.Zero, IntPtr.Zero);
Win32DestroyWindow(window);
