In response to IBM's upcoming release of OS/2 2.0, Microsoft has made available a Windows 3.1 environment with several enhancements to 3.0, such as the ability to display scalable TrueType fonts (developed jointly with Apple). Changes in the new version mainly included bug fixes and the addition of media support. One of the removed features of the overlay was real-world operation, which meant that the weakest processor capable of running the new Windows was the 80286 chip. In 1992 Microsoft also released version 3.11, which contained all the fixes and updates made since the release of 3.1. About the same time Windows for Workgroups debuted, which was available both as an add-on to the already installed 3.1 environment, and a standalone product, containing Windows overlay and network extensions. Windows for Workgroups used streamlined network drivers and protocol stacks, and allowed for work in what was then a peer-to-peer local network. One of the optional components of WfW was the "Wolverine" TCP/IP protocol stack, allowing easy access to the Internet over the company's network. There were two versions of Windows for Workgroups - 3.1 and 3.11, of which version 3.11 ran only in extended mode on 386 processors, so it required a processor no weaker than 80386 SX.
These versions sold as well as 3.0. Although OS/2 features such as long file names, desktop work, and malware protection were not available, Microsoft quickly took over the PC operating systems and graphical user interfaces market and the Windows API became the standard in consumer application design.
Windows 3.x included the "Multimedia Edition", which was aimed at multimedia computers (the system itself included programs and tools that allowed to open multimedia).
