Windows 3.1 (originally codenamed Janus), was released on March 18, 1992, and included a TrueType Font system (and a set of highly legible fonts already installed), which effectively made Windows a serious desktop publishing platform for the first time out of the box. (Similar functionality was available for Windows 3.0 through the Adobe Type Manager (ATM) font system from Adobe.) This version of Windows also included a relatively simple antivirus program called Microsoft Anti-Virus for Windows, abbreviated MSAV; this later became known as the antivirus program that detected the Windows 95 upgrade program as a computer virus.
Windows 3.1 was designed to have a large degree of backward compatibility with older Windows platforms. As with Windows 3.0, version 3.1 had File Manager and Program Manager. Windows 3.1 was also the last version of Windows not to use the right click or to have a ready 'copy and paste' method. To copy something to a diskette the user had to use the File Manager.
A special version named Windows 3.1 for Central and Eastern Europe was released that allowed the use of Cyrillic and had fonts with diacritical marks, characteristic for the Central and Eastern European languages.
TCP/IP networking under Windows 3.x relied on third-party packages, such as Winsock. An add-on package from Microsoft (codenamed Snowball) also provided TCP/IP support in Windows for Workgroups but it was not generally available.
