Microsoft Office is an office suite of desktop applications, servers and services for the Microsoft Windows and OS Xoperating systems. It was first announced by Bill Gates of Microsoft on August 1, 1988 at COMDEX in Las Vegas. Initially a marketing term for a bundled set of applications, the first version of Office contained Microsoft Word, Microsoft Excel andMicrosoft PowerPoint.
