 The desktop metaphor was popularized on commercial personal computers by the original Macintosh from Apple in 1984, and was popularized further by Windows from Microsoft since the 1990s., the most popular desktop environments are descendants of these earlier environments, including the Aero environment used in Windows Vista and Windows 7, and the Aqua environment used in macOS.When compared with the X-based desktop environments available for Unix-like operating systems such as Linux and FreeBSD, the proprietary desktop environments included with Windows and macOS have relatively fixed layouts and static features, with highly integrated "seamless" designs that aim to provide mostly consistent customer experiences across installations.
