What is Windows Aero?
Windows Aero is a technology introduced with Windows Vista. Aero creates the transparent decoration effects, e.g. for start menu, task bar, window headers, etc. Aero also takes care of inter display synchronization, so if Aero is enabled e tearing effects are not visible any more.
Windows Aero is the technical foundation to embed warping and blending into the Windows desktop. If there is no hardware support for warp and blend (NVIDIA Quadro or AMD Firepro graphics cards), Windows Aero is the only solution for realizing warping and blending for any application.
Windows Aero is activated by selecting a "Windows Theme". See a video how to to select an Aero theme here:
