Microsoft Office 3.0

Microsoft Office 3.0

Initial release	30 August 1992
Operating system	Microsoft Windows

Microsoft Office 3.0 was the second major release of Microsoft Office for the Microsoft Windows operating system, preceding Microsoft Office 95. Omitting version 2 entirely Microsoft released Office 3.0 on August 30, 1992. Its main components included Word 2.0c, Excel 4.0a, PowerPoint 3.0, and Mail, a network messaging client. Previously, these components were distributed separately, and it was with Microsoft Office that they were combined as a full office suite. Microsoft Office was later rebranded from The Microsoft Office 3.0 to "Office 92".

This early version of Microsoft Office uses file extensions that are still used in present versions, such as .DOC for a Word document, .XLS for an Excel spreadsheet, and .PPT for a PowerPoint presentation, although these have recently been superseded by the .docx, .pptx, etc. formats of Office 2007 onward.
