Windows Vista Home Basic edition does not come with Windows Aero interface which provides glass transparency effects Aero experience in Windows Vista (features comparison), as Microsoft intended for Vista Home Basic edition to be used in home for basic computing needs only. Thus a lot of functionalities and features have been stripped off Vista HB compared with premium version of Vista, including Aero desktop experience.
