Please note that we have only compiled the major releases of Windows for you. For example, Windows for Workgroup, Windows NT, and extensions to a major build like 2.1, 3.1, etc... will not be covered for the sake of repetition. In addition, we will only present the client versions of the Windows operating system, not the server operating systems (Windows Server).
