ignore it then
Aero is the hardware accelerated desktop for Windows with its fancy glass like transparent taskbar and program title bars.
It is also responsible for moving windows being nice and smooth without that page tearing effect that can happen without hardware acceleration on an operating system.
Despite being complained about(resource hog/ect), I personally think it was one of the best things they did to improve the users experience on windows(starting with Vista and newer)http://en.wikipedia.org/wiki/Windows_Aero
MS must not like to too much because lots of the visual appeal(transparent window title bars ect) is being removed from Win8
