In June, Microsoft will unveil the first Release Preview of Windows 8, its next major version of the Windows (client). Some of the latest screenshots of the teething operating system made it to the web, and reveal some significant changes to the UI, apart from the Metro UI. With its Desktop workspace, Windows 8 embraces a new UI design, that does away with the glassy Aero design that was introduced with Windows Vista. What we have instead, are minimalist titlebars with centered window titles, flat window control buttons, and a blending of the titlebar's color with that of the other menubars. Microsoft justifies the design change by calling the older Aero UI "dated and cheesy." Microsoft assured users that it will assist in the transition between the two UIs, apart from the major change that Metro is.
