===Windows Vista===
In Windows Vista, all Windows applications including GDI and GDI+ applications run in the new compositing engine, [[Desktop Window Manager]] (DWM), which is hardware-accelerated. As such, the GDI itself is no longer hardware-accelerated.<ref>[http://msdn.microsoft.com/en-us/library/windows/desktop/ff729480 MSDN: Comparing Direct2D and GDI Hardware Acceleration]</ref><ref name="Greg SchechterBlog">[http://blogs.msdn.com/greg_schechter/archive/2006/03/10/549310.aspx GDI is not hardware accelerated in Windows Vista]</ref><ref>[http://blogs.msdn.com/seema/archive/2006/10/25/layered-windows-sw-is-sometimes-faster-than-hw.aspx Layered windows...SW is sometimes faster than HW]. Avalite on MSDN Blogs.</ref> Because of the nature of the composition operations, window moves can be faster or more responsive because underlying content does not need to be re-rendered by the application.<ref name="Greg SchechterBlog" />
