This manual's cover states: "For Distribution Only With a New PC."

Although the title suggests a singular "User's Guide" (User's Guide: Microsoft Windows for Workgroups Operating System Version 3.11), it really consists of two volumes in one.

Volume 1 is called Microsoft Workgroup Add-On for Windows: User's Guide for the Microsoft Windows Operating System, (1993). This volume provides the reader with information about enhancements and new applications for Windows for Workgroups Version 3.11. The enhancements and new applications are all about networking, mailing, and faxing

Volume 2 is called User's Guide: Microsoft Windows Operating System Version 3.1 (1993). This volume provides the reader with the information needed to use Microsoft Windows Version 3.1, such as, starting and stopping Windows, using the Program Manager, File Manager, and Print Manager, using the Control Panel, and switching between applications (both Windows and MS-DOS applications).

A Comprehensive Index at the end of the 2-in-1 manual lists entries for both guides. Each volume contains its own Table of Contents.

Microsoft Windows for Workgroups (WFW) 3.11 was released in 1993. It supported full 32-bit file access, TCP/IP networking, and file caching. WFW was not integrated with DOS. It was like any other application that ran on DOS. WFW was superseded two years later by Windows 95, Microsoft's first attempt to integrate MS-DOS and Windows into a single product.

As of October 2008, WFW 3.11 is still being sold. Microsoft is selling it in their embedded product line, but not for long. In July 2008, Microsoft announced that as of November 1, 2008, WFW 3.11 would finally go away.

Incidentally, WFW 3.11 was the first Windows operating system to include Minesweeper.
