Windows Aero是从Windows Vista开始使用的新型用户界面，透明玻璃感让用户一眼贯穿。「Aero」为四个英文单字的首字母缩略字：Authentic（真实）、Energetic（动感）、Reflective（反射）及Open（开阔）。意为Aero界面是具立体感、令人震撼、具透视感和阔大的用户界面。除了透明的接口外，Windows Aero也包含了即时缩略图、即时动画等窗口特效，吸引用户的目光。

针对Windows Vista，Aero接口只预载家用高端版、商用入门版、商用高端版和旗舰版等版本中，至于Windows 7，只预载在家用高端版、专业版、商用版与旗舰版中。但是微软于其团队 blog 中已宣布，Windows 8 RTM中，桌面已抛弃Aero Glass 效果而恢复以往平面式设计，但部分Aero设计，如Aero Snap和透明任务栏仍然保留，不过可以用第三方程序来修改，Windows 10恢复部分Aero效果。

Windows Aero (a backronym for Authentic, Energetic, Reflective, and Open, or simply AERO or Aero), also known as Aero Glass, is a set of interface and design guidelines that were introduced by the Windows Vista operating system. The changes made in the Aero interface affected many elements of the Windows interface, including the incorporation of a new look, along with changes in interface guidelines reflecting appearance, layout, and the phrasing and tone of instructions and other text in applications.
